Question

Which of the following mathematical operations does not satisfy the closure propery for whole numbers?

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

Answer 1

Answer: (A), (C)

The correct options are
A Subtraction
C Division

Closure property states that the operands(numbers) and the result of the operation should belong to the same group.
But this does not hold good for subtraction and division of whole numbers.

Ex: $\to$ 5 - 8 = -3 (not a whole number)
$\frac{5}{8}$ = 0.625 (not a whole number)
