properties of relations calculator

example: consider $G: \mathbb{R} \to \mathbb{R}$ by $xGy\iffx > y$. }\) ${\left. Let \({\cal T}$ be the set of triangles that can be drawn on a plane. It is not irreflexive either, because $5\mid(10+10)$. Let us assume that X and Y represent two sets. More precisely, $R$ is transitive if $x\,R\,y$ and $y\,R\,z$ implies that $x\,R\,z$. Assume (x,y) R ( x, y) R and (y,x) R ( y, x) R. Consider the relation $R$ on $\mathbb{Z}$ defined by $xRy\iff5 \mid (x-y)$. 4. Draw the directed (arrow) graph for $A$. Similarly, for all y in the domain of f^(-1), f(f^(-1)(y)) = y. 9 Important Properties Of Relations In Set Theory. Antisymmetric if every pair of vertices is connected by none or exactly one directed line. Reflexive: for all , 2. You can also check out other Maths topics too. Operations on sets calculator. Relation to ellipse A circle is actually a special case of an ellipse. $ R=X\times Y $ denotes a universal relation as each element of X is connected to each and every element of Y. For example, (2 \times 3) \times 4 = 2 \times (3 . To put it another way, a relation states that each input will result in one or even more outputs. For the relation in Problem 6 in Exercises 1.1, determine which of the five properties are satisfied. The directed graph for the relation has no loops. The empty relation between sets X and Y, or on E, is the empty set . In other words, a relations inverse is also a relation. We have $(2,3)\in R$ but $(3,2)\notin R$, thus $R$ is not symmetric. I am having trouble writing my transitive relation function. For any $a\neq b$, only one of the four possibilities $(a,b)\notin R$, $(b,a)\notin R$, $(a,b)\in R$, or $(b,a)\in R$ can occur, so $R$ is antisymmetric. can be a binary relation over V for any undirected graph G = (V, E). The relation $U$ on the set $\mathbb{Z}^*$ is defined as \[a\,U\,b \,\Leftrightarrow\, a\mid b. The properties of relations are given below: Each element only maps to itself in an identity relationship. Download the app now to avail exciting offers! Example $\PageIndex{6}\label{eg:proprelat-05}$, The relation $U$ on $\mathbb{Z}$ is defined as \[a\,U\,b \,\Leftrightarrow\, 5\mid(a+b). Yes, if $X$ is the brother of $Y$ and $Y$ is the brother of $Z$ , then $X$ is the brother of $Z.$, Example $\PageIndex{2}\label{eg:proprelat-02}$, Consider the relation $R$ on the set $A=\{1,2,3,4\}$ defined by \[R = \{(1,1),(2,3),(2,4),(3,3),(3,4)\}.\]. \nonumber\]. Find out the relationships characteristics. What are the 3 methods for finding the inverse of a function? $a-a=0$. It is denoted as $ R=\varnothing $, Lets consider an example, $ P=\left\{7,\ 9,\ 11\right\} $ and the relation on $ P,\ R=\left\{\left(x,\ y\right)\ where\ x+y=96\right\} $ Because no two elements of P sum up to 96, it would be an empty relation, i.e R is an empty set, $ R=\varnothing $. Transitive if for every unidirectional path joining three vertices $a,b,c$, in that order, there is also a directed line joining $a$ to $c$. Symmetric: implies for all 3. Before I explain the code, here are the basic properties of relations with examples. Hence it is not reflexive. Legal. For each of the following relations on $\mathbb{N}$, determine which of the five properties are satisfied. Boost your exam preparations with the help of the Testbook App. property an attribute, quality, or characteristic of something reflexive property a number is always equal to itself a = a The contrapositive of the original definition asserts that when $a\neq b$, three things could happen: $a$ and $b$ are incomparable ($\overline{a\,W\,b}$ and $\overline{b\,W\,a}$), that is, $a$ and $b$ are unrelated; $a\,W\,b$ but $\overline{b\,W\,a}$, or. It may sound weird from the definition that $W$ is antisymmetric: \[(a \mbox{ is a child of } b) \wedge (b\mbox{ is a child of } a) \Rightarrow a=b, \label{eqn:child}\] but it is true! A function basically relates an input to an output, theres an input, a relationship and an output. More ways to get app For example, let $ P=\left\{1,\ 2,\ 3\right\},\ Q=\left\{4,\ 5,\ 6\right\}\ and\ R=\left\{\left(x,\ y\right)\ where\ xb$ and $b>c$ then $a>c$ is true for all $a,b,c\in \mathbb{R}$,the relation $G$ is transitive. The relation ${R = \left\{ {\left( {1,2} \right),\left( {1,3} \right),}\right. For each pair (x, y) the object X is Get Tasks. = The elements in the above question are 2,3,4 and the ordered pairs of relation R, we identify the associations.\( \left(2,\ 2\right) $ where 2 is related to 2, and every element of A is related to itself only. It is reflexive (hence not irreflexive), symmetric, antisymmetric, and transitive. Analyze the graph to determine the characteristics of the binary relation R. 5. The cartesian product of a set of N elements with itself contains N pairs of (x, x) that must not be used in an irreflexive relationship. Since $a|a$ for all $a \in \mathbb{Z}$ the relation $D$ is reflexive. It is clearly irreflexive, hence not reflexive. So, $5 \mid (a-c)$ by definition of divides. In math, a quadratic equation is a second-order polynomial equation in a single variable. Define a relation $P$ on ${\cal L}$ according to $(L_1,L_2)\in P$ if and only if $L_1$ and $L_2$ are parallel lines. (b) reflexive, symmetric, transitive Soil mass is generally a three-phase system. The identity relation rule is shown below. Exercise $\PageIndex{10}\label{ex:proprelat-10}$, Exercise $\PageIndex{11}\label{ex:proprelat-11}$. { (1,1) (2,2) (3,3)} hands-on exercise $\PageIndex{6}\label{he:proprelat-06}$, Determine whether the following relation $W$ on a nonempty set of individuals in a community is reflexive, irreflexive, symmetric, antisymmetric, or transitive: \[a\,W\,b \,\Leftrightarrow\, \mbox{$a$ and $b$ have the same last name}. Since no such counterexample exists in for your relation, it is trivially true that the relation is antisymmetric. Instead of using two rows of vertices in the digraph that represents a relation on a set $A$, we can use just one set of vertices to represent the elements of $A$. It is sometimes convenient to express the fact that particular ordered pair say (x,y) E R where, R is a relation by writing xRY which may be read as "x is a relation R to y". No, Jamal can be the brother of Elaine, but Elaine is not the brother of Jamal. To calculate the inverse of a function, swap the x and y variables then solve for y in terms of x. A binary relation $R$ on a set $A$ is said to be antisymmetric if there is no pair of distinct elements of $A$ each of which is related by $R$ to the other. For example, $ P=\left\{5,\ 9,\ 11\right\} $ then $ I=\left\{\left(5,\ 5\right),\ \left(9,9\right),\ \left(11,\ 11\right)\right\} $, An empty relation is one where no element of a set is mapped to another sets element or to itself. $-k \in \mathbb{Z}$ since the set of integers is closed under multiplication. All these properties apply only to relations in (on) a (single) set, i.e., in AAfor example. I am trying to use this method of testing it: transitive: set holds to true for each pair(e,f) in b for each pair(f,g) in b if pair(e,g) is not in b set holds to false break if holds is false break $S_1\cap S_2=\emptyset$ and$S_2\cap S_3=\emptyset$, but$S_1\cap S_3\neq\emptyset$. Functions are special types of relations that can be employed to construct a unique mapping from the input set to the output set. $A_1=\{(x,y)\mid x$ and $y$ are relatively prime$\}$, $A_2=\{(x,y)\mid x$ and $y$ are not relatively prime$\}$, $V_3=\{(x,y)\mid x$ is a multiple of $y\}$. For example, $5\mid(2+3)$ and $5\mid(3+2)$, yet $2\neq3$. Equations Inequalities System of Equations System of Inequalities Basic Operations Algebraic Properties Partial Fractions Polynomials Rational Expressions Sequences Power Sums Interval Notation Pi . Let ${\cal L}$ be the set of all the (straight) lines on a plane. , and X n is a subset of the n-ary product X 1 . X n, in which case R is a set of n-tuples. Thus, $U$ is symmetric. Reflexive - R is reflexive if every element relates to itself. The relation $R$ is said to be reflexive if every element is related to itself, that is, if $x\,R\,x$ for every $x\in A$. Since$aRb$,$5 \mid (a-b)$ by definition of $R.$ Bydefinition of divides, there exists an integer $k$ such that \[5k=a-b. For matrixes representation of relations, each line represent the X object and column, Y object. If $R$ is a relation from $A$ to $A$, then $R\subseteq A\times A$; we say that $R$ is a relation on $\mathbf{A}$. The matrix MR and its transpose, MTR, coincide, making the relationship R symmetric. image/svg+xml. If R signifies an identity connection, and R symbolizes the relation stated on Set A, then, then, $ R=\text{ }\{\left( a,\text{ }a \right)/\text{ }for\text{ }all\text{ }a\in A\} $, That is to say, each member of A must only be connected to itself. In each example R is the given relation. \nonumber\], hands-on exercise $\PageIndex{5}\label{he:proprelat-05}$, Determine whether the following relation $V$ on some universal set $\cal U$ is reflexive, irreflexive, symmetric, antisymmetric, or transitive: \[(S,T)\in V \,\Leftrightarrow\, S\subseteq T. \nonumber\], Example $\PageIndex{7}\label{eg:proprelat-06}$, Consider the relation $V$ on the set $A=\{0,1\}$ is defined according to \[V = \{(0,0),(1,1)\}. \nonumber\]. The relation "is perpendicular to" on the set of straight lines in a plane. This shows that $R$ is transitive. Wave Period (T): seconds. Free Algebraic Properties Calculator - Simplify radicals, exponents, logarithms, absolute values and complex numbers step-by-step. Transitive Property The Transitive Property states that for all real numbers if and , then . For each pair (x, y) the object X is. Thus the relation is symmetric. example: consider $D: \mathbb{Z} \to \mathbb{Z}$ by $xDy\iffx|y$. Hence, $T$ is transitive. Properties: A relation R is reflexive if there is loop at every node of directed graph. Relations properties calculator RelCalculator is a Relation calculator to find relations between sets Relation is a collection of ordered pairs. Thus, R is identity. a) D1 = {(x, y) x + y is odd } Let $S$ be a nonempty set and define the relation $A$ on $\scr{P}$$(S)$ by \[(X,Y)\in A \Leftrightarrow X\cap Y=\emptyset.\] It is clear that $A$ is symmetric. There are 3 methods for finding the inverse of a function: algebraic method, graphical method, and numerical method. I would like to know - how. If it is reflexive, then it is not irreflexive. Therefore$U$ is not an equivalence relation, Determine whether the following relation $V$ on some universal set $\cal U$ is an equivalence relation: \[(S,T)\in V \,\Leftrightarrow\, S\subseteq T.\], Example $\PageIndex{7}\label{eg:proprelat-06}$, Consider the relation $V$ on the set $A=\{0,1\}$ is defined according to \[V = \{(0,0),(1,1)\}.\]. The relation "is parallel to" on the set of straight lines. A relation $R$ on $A$ is transitiveif and only iffor all $a,b,c \in A$, if $aRb$ and $bRc$, then $aRc$. i.e there is $\{a,c\}\right arrow\{b}\}$ and also$\{b\}\right arrow\{a,c}\}$. Transitive: Let $a,b,c \in \mathbb{Z}$ such that $aRb$ and $bRc.$ We must show that $aRc.$ A directed line connects vertex $a$ to vertex $b$ if and only if the element $a$ is related to the element $b$. Draw the directed graph for $A$, and find the incidence matrix that represents $A$. By going through all the ordered pairs in $R$, we verify that whether $(a,b)\in R$ and $(b,c)\in R$, we always have $(a,c)\in R$ as well. Math is all about solving equations and finding the right answer. Set theory is a fundamental subject of mathematics that serves as the foundation for many fields such as algebra, topology, and probability. a) $A_1=\{(x,y)\mid x \mbox{ and } y \mbox{ are relatively prime}\}$. Exercise $\PageIndex{7}\label{ex:proprelat-07}$. $\therefore R $ is transitive. For instance, R of A and B is demonstrated. $B$ is a relation on all people on Earth defined by $xBy$ if and only if $x$ is a brother of $y.$. Reflexivity. See Problem 10 in Exercises 7.1. Thus, $U$ is symmetric. For each relation in Problem 1 in Exercises 1.1, determine which of the five properties are satisfied. Relations. We have shown a counter example to transitivity, so $A$ is not transitive. The transitivity property is true for all pairs that overlap. The squares are 1 if your pair exist on relation. Let $ A=\left\{2,\ 3,\ 4\right\} $ and R be relation defined as set A, $ R=\left\{\left(2,\ 2\right),\ \left(3,\ 3\right),\ \left(4,\ 4\right)\right\} $, Verify R is identity. More specifically, we want to know whether $(a,b)\in \emptyset \Rightarrow (b,a)\in \emptyset$. If a relation $R$ on $A$ is both symmetric and antisymmetric, its off-diagonal entries are all zeros, so it is a subset of the identity relation. \nonumber\] Properties of Relations. Identity relation maps an element of a set only to itself whereas a reflexive relation maps an element to itself and possibly other elements. In a matrix $M = \left[ {{a_{ij}}} \right]$ of a transitive relation $R,$ for each pair of $\left({i,j}\right)-$ and $\left({j,k}\right)-$entries with value $1$ there exists the $\left({i,k}\right)-$entry with value $1.$ The presence of $1'\text{s}$ on the main diagonal does not violate transitivity. It is clear that $W$ is not transitive. Relation means a connection between two persons, it could be a father-son relation, mother-daughter, or brother-sister relations. The relation $\ge$ ("is greater than or equal to") on the set of real numbers. $ A=\left\{x,\ y,\ z\right\} $, Assume R is a transitive relation on the set A. Depth (d): : Meters : Feet. Then $ R=\left\{\left(x,\ y\right),\ \left(y,\ z\right),\ \left(x,\ z\right)\right\} $v, That instance, if x is connected to y and y is connected to z, x must be connected to z., For example,P ={a,b,c} , the relation R={(a,b),(b,c),(a,c)}, here a,b,c P. Consider the relation R, which is defined on set A. R is an equivalence relation if the relation R is reflexive, symmetric, and transitive. Thanks for the feedback. Cartesian product denoted by * is a binary operator which is usually applied between sets. A function can only have an inverse if it is one-to-one so that no two elements in the domain are matched to the same element in the range. The relation $S$ on the set $\mathbb{R}^*$ is defined as \[a\,S\,b \,\Leftrightarrow\, ab>0. Set theory and types of set in Discrete Mathematics, Operations performed on the set in Discrete Mathematics, Group theory and their type in Discrete Mathematics, Algebraic Structure and properties of structure, Permutation Group in Discrete Mathematics, Types of Relation in Discrete Mathematics, Rings and Types of Rings in Discrete Mathematics, Normal forms and their types | Discrete Mathematics, Operations in preposition logic | Discrete Mathematics, Generally Accepted Accounting Principles MCQs, Marginal Costing and Absorption Costing MCQs. It is not transitive either. To check symmetry, we want to know whether $a\,R\,b \Rightarrow b\,R\,a$ for all $a,b\in A$. \nonumber\]\[5k=b-c. \nonumber\] Adding the equations together and using algebra: \[5j+5k=a-c \nonumber\]\[5(j+k)=a-c. \nonumber\] $j+k \in \mathbb{Z}$since the set of integers is closed under addition. I have written reflexive, symmetric and anti-symmetric but cannot figure out transitive. Yes. \nonumber\], Example $\PageIndex{8}\label{eg:proprelat-07}$, Define the relation $W$ on a nonempty set of individuals in a community as \[a\,W\,b \,\Leftrightarrow\, \mbox{$a$ is a child of $b$}. Exercise $\PageIndex{1}\label{ex:proprelat-01}$. Consider the relation R, which is specified on the set A. The digraph of a reflexive relation has a loop from each node to itself. It follows that $V$ is also antisymmetric. A Binary relation R on a single set A is defined as a subset of AxA. Even though the name may suggest so, antisymmetry is not the opposite of symmetry. A relation is anequivalence relation if and only if the relation is reflexive, symmetric and transitive. Example $\PageIndex{1}\label{eg:SpecRel}$. Hence, $T$ is transitive. This calculator solves for the wavelength and other wave properties of a wave for a given wave period and water depth. $\therefore R $ is symmetric. Sets are collections of ordered elements, where relations are operations that define a connection between elements of two sets or the same set. A quantity or amount. Let ${\cal T}$ be the set of triangles that can be drawn on a plane. a) $U_1=\{(x,y)\mid 3 \mbox{ divides } x+2y\}$, b) $U_2=\{(x,y)\mid x - y \mbox{ is odd } \}$, (a) reflexive, symmetric and transitive (try proving this!) Already have an account? Here's a quick summary of these properties: Commutative property of multiplication: Changing the order of factors does not change the product. If there exists some triple $a,b,c \in A$ such that $\left( {a,b} \right) \in R$ and $\left( {b,c} \right) \in R,$ but $\left( {a,c} \right) \notin R,$ then the relation $R$ is not transitive. Algebraic Properties Calculator Algebraic Properties Calculator Simplify radicals, exponents, logarithms, absolute values and complex numbers step-by-step full pad Examples Next up in our Getting Started maths solutions series is help with another middle school algebra topic - solving. The cartesian product of X and Y is thus given as the collection of all feasible ordered pairs, denoted by $X\times Y.=\left\{(x,y);\forall x\epsilon X,\ y\epsilon Y\right\}$. Immunology Tutors; Series 32 Test Prep; AANP - American Association of Nurse Practitioners Tutors . The relation $R = \left\{ {\left( {2,1} \right),\left( {2,3} \right),\left( {3,1} \right)} \right\}$ on the set $A = \left\{ {1,2,3} \right\}.$. }\) ${\left. 2023 Calcworkshop LLC / Privacy Policy / Terms of Service, What is a binary relation? Irreflexive: NO, because the relation does contain (a, a). The relation \(V$ is reflexive, because $(0,0)\in V$ and $(1,1)\in V$. (Problem #5i), Show R is an equivalence relation (Problem #6a), Find the partition T/R that corresponds to the equivalence relation (Problem #6b). So we have shown an element which is not related to itself; thus $S$ is not reflexive. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. The empty relation is the subset $\emptyset$. The properties of relations are given below: Identity Relation Empty Relation Reflexive Relation Irreflexive Relation Inverse Relation Symmetric Relation Transitive Relation Equivalence Relation Universal Relation Identity Relation Each element only maps to itself in an identity relationship. Through these experimental and calculated results, the composition-phase-property relations of the Cu-Ni-Al and Cu-Ti-Al ternary systems were established. The relation $V$ is reflexive, because $(0,0)\in V$ and $(1,1)\in V$. (c) Here's a sketch of some ofthe diagram should look: Some of the notable applications include relational management systems, functional analysis etc. The relation $U$ is not reflexive, because $5\nmid(1+1)$. It is clearly reflexive, hence not irreflexive. \nonumber\], and if $a$ and $b$ are related, then either. A non-one-to-one function is not invertible. Let ${\cal L}$ be the set of all the (straight) lines on a plane. Example $\PageIndex{2}\label{eg:proprelat-02}$, Consider the relation $R$ on the set $A=\{1,2,3,4\}$ defined by \[R = \{(1,1),(2,3),(2,4),(3,3),(3,4)\}. brother than" is a symmetric relationwhile "is taller than is an We can express this in QL as follows: R is symmetric (x)(y)(Rxy Ryx) Other examples: The relation R defined by "aRb if a is not a sister of b". a) B1 = {(x, y) x divides y} b) B2 = {(x, y) x + y is even } c) B3 = {(x, y) xy is even } Answer: Exercise 6.2.4 For each of the following relations on N, determine which of the three properties are satisfied. Exercise $\PageIndex{4}\label{ex:proprelat-04}$. Relations properties calculator An equivalence relation on a set X is a subset of XX, i.e., a collection R of ordered pairs of elements of X, satisfying certain properties. }\) In fact, the term equivalence relation is used because those relations which satisfy the definition behave quite like the equality relation. = We must examine the criterion provided under for every ordered pair in R to see if it is transitive, the ordered pair $ \left(a,\ b\right),\ \left(b,\ c\right)\rightarrow\left(a,\ c\right) $, where in here we have the pair $ \left(2,\ 3\right) $, Thus making it transitive. Symmetric if $M$ is symmetric, that is, $m_{ij}=m_{ji}$ whenever $i\neq j$. It will also generate a step by step explanation for each operation. If $\frac{a}{b}, \frac{b}{c}\in\mathbb{Q}$, then $\frac{a}{b}= \frac{m}{n}$ and $\frac{b}{c}= \frac{p}{q}$ for some nonzero integers $m$, $n$, $p$, and $q$. See also Equivalence Class, Teichmller Space Explore with Wolfram|Alpha More things to try: 1/ (12+7i) d/dx Si (x)^2 If the discriminant is positive there are two solutions, if negative there is no solution, if equlas 0 there is 1 solution. Apply it to Example 7.2.2 to see how it works. For a symmetric relation, the logical matrix $M$ is symmetric about the main diagonal. 1. Thus, to check for equivalence, we must see if the relation is reflexive, symmetric, and transitive. A binary relation $R$ on a set $A$ is called irreflexive if $aRa$ does not hold for any $a \in A.$ This means that there is no element in $R$ which is related to itself. That is, (x,y) ( x, y) R if and only if x x is divisible by y y We will determine if R is an antisymmetric relation or not. Properties of Relations Calculus Set Theory Properties of Relations Home Calculus Set Theory Properties of Relations A binary relation R defined on a set A may have the following properties: Reflexivity Irreflexivity Symmetry Antisymmetry Asymmetry Transitivity Next we will discuss these properties in more detail. The relation $T$ is symmetric, because if $\frac{a}{b}$ can be written as $\frac{m}{n}$ for some integers $m$ and $n$, then so is its reciprocal $\frac{b}{a}$, because $\frac{b}{a}=\frac{n}{m}$. For instance, the incidence matrix for the identity relation consists of 1s on the main diagonal, and 0s everywhere else. High School Math Solutions - Quadratic Equations Calculator, Part 1. Select an input variable by using the choice button and then type in the value of the selected variable. Reflexive Property - For a symmetric matrix A, we know that A = A T.Therefore, (A, A) R. R is reflexive. We find that $R$ is. A good way to understand antisymmetry is to look at its contrapositive: \[a\neq b \Rightarrow \overline{(a,b)\in R \,\wedge\, (b,a)\in R}. It is clearly symmetric, because $(a,b)\in V$ always implies $(b,a)\in V$. The relation $=$ ("is equal to") on the set of real numbers. Because of the outward folded surface (after . Legal. For instance, a subset of AB, called a "binary relation from A to B," is a collection of ordered pairs (a,b) with first components from A and second components from B, and, in particular, a subset of AA is called a "relation on A." For a binary relation R, one often writes aRb to mean that (a,b) is in RR. }\) ${\left. If it is irreflexive, then it cannot be reflexive. \nonumber\] Thus, if two distinct elements \(a$ and $b$ are related (not every pair of elements need to be related), then either $a$ is related to $b$, or $b$ is related to $a$, but not both. Associative property of multiplication: Changing the grouping of factors does not change the product. Equations Inequalities System of Equations System of Inequalities Basic Operations Algebraic Properties Partial Fractions Polynomials Rational Expressions Sequences Power Sums Interval . Exploring the properties of relations including reflexive, symmetric, anti-symmetric and transitive properties.Textbook: Rosen, Discrete Mathematics and Its . It is not antisymmetric unless $|A|=1$. Then, R = { (a, b), (b, c), (a, c)} That is, If "a" is related to "b" and "b" is related to "c", then "a" has to be related to "c". Thanks for the help! If an antisymmetric relation contains an element of kind $\left( {a,a} \right),$ it cannot be asymmetric. It sounds similar to identity relation, but it varies. A compact way to define antisymmetry is: if $x\,R\,y$ and $y\,R\,x$, then we must have $x=y$. Substitution Property If , then may be replaced by in any equation or expression. The calculator computes ratios to free stream values across an oblique shock wave, turn angle, wave angle and associated Mach numbers (normal components, M n , of the upstream). }\) ${\left. A quadratic equation has two solutions if the discriminant b^2 - 4ac is positive. Define the relation \(R$ on the set $\mathbb{R}$ as \[a\,R\,b \,\Leftrightarrow\, a\leq b.\] Determine whether $R$ is reflexive, symmetric,or transitive. Exercise $\PageIndex{3}\label{ex:proprelat-03}$.
