Answer 2

commutative property of addition

Explanation:

Dylan is evaluating the expression 13+19+7+10. At one step in his work, Dylan rewrites the equation as 13+7+19+10

13+19+7+10 = 13+7+19+10

commutative property of addition statest that

a + b = b+a

When the order of terms are changed in addition , it will change the value.

the value remains the same.

Dylan rewrites the expression by changing the order of terms

So its commutative property of addition
