Consider the steps to simplify the expression. What property of operation is used in Step 2? Expression: - 4 3 7 + 7 - 3 4 7 Step 1: = - 4 3 7 + 7 + (-3 4 7) Step 2: = - 4 3 7 + (-3 4 7) + 7 Step 3: = - 4 + ( - 3 7) + (-3) + ( - 4 7) + 7 Step 4: = - 4 + ( - 3 7) + ( - 4 7) + (-3) + 7 Step 5: = - 4 + (-1) + (-3) + 7 Step 6: = - 8 + 7 Step 7: = - 1

The Commutative Property is used because:

-437 + (-347) + 7

-347 + (-437) + 7

7 + (-437) + (-347)

you could put it any order and get the same outcome.
