Question

Which of the following operations are not commutative for whole numbers?

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

Answer 1

Answer: (B), (C)

The correct options are
B

Subtraction

C

Division

Commutative property states that any finite sum or product is not altered by reordering its terms or factors. Among the given operations, addition and multiplication obey commutative property.
6 + 5 = 5 + 6 Commutative property of addition
$6-5\ne 5-6$

So, the commutative property does not hold true for subtraction of whole numbers.
3 $\times$ 6 = 6 $\times$ 3 (Commutative property of multiplication)
$4÷2\ne 2÷4$
So, the commutative property does not hold true for division of whole numbers.
