Division of integers doesn't hold for the closure property, i.e. the quotient of any two integers p and q, may or may not be an integer. Example : (−3) ÷ (−12) = ¼, which is not an integer.
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.
Rules for the Division of Integers for Class 7 Rule 1: The quotient value of two positive integers will always be a positive integer. Rule 2: For two negative integers the quotient value will always be a positive integer.
If the division of two numbers from a set always produces a number in the set, we have closure under division. The set of whole numbers are not closed under division, and the set of integers are not closed under division because they both produce fractions.
The sum of any two integers will always be an integer, i.e. if a and b are any two integers, a + b will be an integer. Closure property of integers under subtraction: The difference between any two integers will always be an integer, i.e. if a and b are any two integers, a – b will be an integer.
Among the various properties of integers, closure property under addition and subtraction states that the sum or difference of any two integers will always be an integer i.e. if x and y are any two integers, x + y and x − y will also be an integer.
Closure Property of Addition for Natural Numbers Addition of any two natural numbers results in a natural number only. We can represent it as a + b = N, where a and b are any two natural numbers, and N is the natural number set. For example, 4+21=25, here all numbers fall under the natural number set.
Closure property We can say that rational numbers are closed under addition, subtraction and multiplication. For example: (7/6)+(2/5) = 47/30. (5/6) – (1/3) = 1/2.
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.
Among the various properties of integers, closure property under addition and subtraction states that the sum or difference of any two integers will always be an integer i.e. if x and y are any two integers, x + y and x − y will also be an integer.
