Dylan is evaluating the expression 13+19+7+10. at one step in his work, dylan rewrites the equation as 13+7+19+10. which property of addition must dylan have used when he evaluated the expression?

commutative property of addition

Step-by-step 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

the 4th choice is the correct one
