Closure Property of Addition for Whole Numbers Addition of any two whole numbers results in a whole number only. We can represent it as a + b = W, where a and b are any two whole numbers, and W is the whole number set. For example, 0+21=21, here all numbers fall under the whole number set.
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.
Definition of Closure Property Example 1: The addition of two real numbers is always a real number. Thus, real numbers are closed under addition. Example 2: Subtraction of two natural numbers may or may not be a natural number. Thus, natural numbers are not closed under subtraction.
The closure property of the division tells that the result of the division of two whole numbers is not always a whole number. Whole numbers are not closed under division i.e., a ÷ b is not always a whole number. From the property, we have, 14 ÷ 7 = 2 (whole number) but 7 ÷ 14 = ½ (not a whole number).
The closure property states that for a given set and a given operation, the result of the operation on any two numbers of the set will also be an element of the set. Here are some examples of closed property: The set of whole numbers is closed under addition and multiplication (but not under subtraction and division)
Closure Property of Whole Numbers Under Addition Set of whole numbers{1, 2, 3, 4, 5...} Pick any two whole numbers from the set 7 and 4 Add 7 + 4 = 11 Does the sum lie in the original set? Yes Inference Whole numbers are closed under addition
Closure Property Examples Add-15 + 2 = -13Sum is an integer Subtract -15 - 2 = -17 Difference is an integer Multiply -15 x 2= -30 Product is an integer Divide -15 / 2 = -7.5 Quotient is not an integer
Closure Property Whole numbers are not closed under division i.e., a ÷ b is not always a whole number. From the property, we have, 14 ÷ 7 = 2 (whole number) but 7 ÷ 14 = ½ (not a whole number).
The set of real numbers is closed under addition. If you add two real numbers, you will get another real number. There is no possibility of ever getting anything other than a real number. For example: 5 + 10 = 15 , 2.5 + 2.5 = 5 , 2 1 2 + 5 = 7 1 2 , 3 + 2 3 = 3 3 , etc.
