Final answer:
The associative property of addition states that the grouping of numbers in an addition expression does not affect the sum.
Step-by-step explanation:
The question is about the associative property of addition in mathematics.
The associative property states that the way in which numbers are grouped in an addition expression does not affect the sum. For example, 8 + (4 + 2) would be equal to (8 + 4) + 2.
Applying the associative property, we can see that both expressions would simplify to 8 + 6, which equals 14.
