Question

subtraction is not commutative for rational numbers give 2 examples ​

Answer 1

Answer:

Subtraction and division are not commutative for rational numbers because while performing these operations, if the order of numbers is changed, then the result also changes.

Examples- 3-2 and 2-3, 45-56 and 56-45

Answer 2

Step-by-step explanation:

subtraction is NOT commutative! We know that for any two numbers a and b: a + b = b + a and ab = ba; however, unless a = b, there are an infinite number of examples or cases which illustrate why subtraction does not have a commutative property, i.e., a - b does not equal b - a!

Let's just take one example of two rational numbers, let a = 2/3 and b = 3/4.
