4) Division of Rational Numbers The closure property states that for any two rational numbers a and b, a ÷ b is also a rational number. The result is a rational number. But we know that any rational number a, a ÷ 0 is not defined. So rational numbers are not closed under division.
The closure property of addition states that when any two elements of a set are added, their sum will also be present in that set. The closure property formula for addition for a given set S is: ∀ a, b ∈ S ⇒ a + b ∈ S.
The closure property of integers does not hold true for the division of integers as the division of two integers may not always result in an integer. For example, we know that 3 and 4 are integers but 3 ÷ 4 = 0.75 which is not an integer. Therefore, the closure property is not applicable to the division of integers.
Closure Property: When something is closed, the output will be the same type of object as the inputs. For instance, adding two integers will output an integer. Adding two polynomials will output a polynomial. Addition, subtraction, and multiplication of integers and polynomials are closed operations.
CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial. Adding polynomials creates another polynomial. Subtracting polynomials creates another polynomail. Multiplying polynomials creates another polynomial.
The closure property for polynomials states that the sum, difference, and product of two polynomials is also a polynomial. However, the closure property does not hold for division, as dividing two polynomials does not always result in a polynomial. Consider the following example: Let P(x)=x2+1 and Q(x)=x.
Polynomials are NOT closed under division (as you may get a variable in the denominator).
When a integer is divided by another integer, the result is not necessarily a integer. Thus, integers are not closed under division.
In math, a closed form of a polynomial means that there is a formula that can be used to find the value of the polynomial for any input value of the variable, without needing to do additional algebraic steps.
