Question

Is subtract associative in rational numbers? Explain with an example

Answer 1

Step-by-step explanation:

Answer: No, subtraction is NOT associative in rational numbers.

Step-by-step explanation: We are asked to state whether subtraction is associative in rational numbers or not. To explain with an example.

Let a, b and c be three rational numbers. Then, according to the associative property, we must have

(a-b)-c=a-(b-c).(a−b)−c=a−(b−c).

The subtraction is NOT associative in rational numbers.

Hence, subtraction is NOT associative in rational numbers.
