Answer:
associative property of addition
Explanation:
There are various properties of mathematics.
One of these is called the associative property of addition, which states that for three numbers a, b, and c:
(a + b) + c = a + (b + c)
Basically, this means that given an addition statement, no matter if we change the order of how we solve it (solving a + b first or solving b + c first), we will still obtain the same result.
Therefore, here, it's clearly a representation of the associative property of addition, and that's the answer.
