Eva is showing her work in simplifying (7.3 – 7.2) – 3.8 + 3.7. in which step did eva make an error?

step 1: (7.3 – 7.2) – 3.8 + 3.7

step 2: 7.3 + (–7.2 – 3.8) + 3.7 (commutative property)

step 3: 7.3 – 11 + 3.7

step 4: 7.3 + 3.7 – 11 (commutative property)

step 5: 11 – 11 = 0
step 2; she wrote commutative instead of distributive
step 4; she wrote commutative instead of distributive
step 4; she wrote commutative instead of associative
step 2; she wrote commutative instead of associative
