−7.9 + 8.2 − 3.4 + 2.1Original problem
1−7.9 + 8.2 + (−3.4) + 2.1Additive inverse
2−7.9 + (−3.4) + 8.2 + 2.1Commutative property
3[−7.9 + (−3.4)] + (8.2 + 2.1)Associative property
4−11.3 + 10.3Simplify
5−1Simplify
She did not make any errors.
Step 1: She wrote −3.4 incorrectly as + (−3.4).
Step 2: She identified changing the order of the numbers as the commutative property, which is incorrect.
Step 3: She identified changing the grouping of the numbers as the associative property, which is incorrect.
