Question
Consider the steps to simplify the expression. What property of operation is used in Step 2?
Expression: -437
+ 7 - 347
Step 1: = -437
+ 7 + (-347
)
Step 2: = -437
+ (-347
) + 7
Step 3: = -4 + (-37
) + (-3) + (-47
) + 7
Step 4: = -4 + (-37
) + (-47
) + (-3) + 7
Step 5: = -4 + (-1) + (-3) + 7
Step 6: = -8 + 7
Step 7: = -1

The property of operation used in Step 2 is the commutative property of addition.
In Step 2, the expression is rearranged so that the terms are written in a different order. The order of addition does not change the result.
