If a, b and c are any three whole numbers, then a + (b + c) = (a + b) + c called?

If a, b and c are any three whole numbers, then a + (b + c) = (a + b) + c called?

Explanation
The Associative property states that the way numbers are grouped in addition or multiplication does not change their sum or product.
Examples:
Addition: a + (b + c) = (a + b) + c
Multiplication: a × (b × c) = (a × b) × c
This property holds true for both addition and multiplication, ensuring that the order in which numbers are grouped does not affect the result.
