The property you're referring to is known as the **Associative Property of Addition**. This property states that when adding three or more numbers, the way in which the numbers are grouped does not change the sum.
In the example you provided:
\( 5 + (3 + 9) = (5 + 3) + 9 \)
Let's break it down:
- On the left side: \( 3 + 9 = 12 \), so \( 5 + 12 = 17 \).
- On the right side: \( 5 + 3 = 8 \), so \( 8 + 9 = 17 \).
Both sides equal 17, thus confirming that the associative property holds true in this case.
