Question

The subtraction of rational numbers is commutative

True

False

Solution

The correct option is **B**

False

For two given numbers a and b,

If a + b = b + a then they are called commutative.

For subtraction a - b should be equal to b - a

If we take any 2 random numbers 2 and −12

a - b = 2 - −12 = 2 + 12 = 212 or 52

b - a = −12 - 2 = −1−42 = −52 which is ≠ 52

Hence , the given statement is false.
