<u>ANSWER</u>
Commutative property of addition.
<u>EXPLANATION</u>
Let a,b be real numbers. The commutative property of addition states that,
If we let a=-10 and b=6, then
Therefore the given expression demonstrates the commutative property of addition.
The commutative property of addition tells us that, the order in which we add two real numbers does not affect the result.
