Which property of operations states that changing the grouping of numbers does not change their sum?

Understand the Problem

The question is asking which mathematical property explains that the way numbers are grouped in addition does not affect their total sum. This is referring to a fundamental property of addition.

More Information

The associative property of addition ensures that when you add several numbers, you can rearrange their grouping without affecting the sum.

Tips

Do not confuse the associative property with the commutative property, which involves changing the order of the numbers, not their grouping.
