Step 2; she wrote commutative instead of associative.
Explanation:
An associative property of addition is a rule that states that, the sum of three (3) or more numbers will always be the same irrespective of how these numbers are grouped.
This ultimately implies that, re-grouping three (3) or more numbers and adding them will give the same answer or end result (outcome).
Mathematically, the associative property of addition is given by the formula;

Applying the above rule to the question, we have;

Hence, we would have the correct step written as;
Step 2: 7.3 + (-7.2 − 3.8) + 3.7 (associative property of addition).
In conclusion, Eva should have written associative property in Step 2 instead of commutative property.
