Question

does not follow the property of closure for integers.

• A. Addition
• B. Subtraction
• C. Multiplication
• D. Division

Answer 1

The correct option is D Division

Addition, subtraction and multiplication follow the property of closure for integers as the sum, difference and multiplication of any two integers is always an integer.
Example: Let the two integers be 2 and 5.
2 + 5 = 7, which is also an integer.
2 - 5 = -3, which is also an integer, and
2 $\times 5$ = 10, which is also an intger.

Division does not follow the property of closure for integers because the division of two integers may not always results in an integer.
Example: $2÷5=\frac{2}{5},$ which is not an integer.
