How can associative, commutative, & distributive properties be applied when performing operations on complex numbers?

Associative: (a+b) + c=a + (b+c)

commutative: a+b=b+a

distributive: a (b+c) = ab+ac

easy, so example 2 (3+5i) + (7-2i)

distributive

6+10i+7-2i

maybe associative if yo did (6+10i) + (7-2i) to (6+7) + (10i-2i)

anyay commutative

6+7+10i-2i

13+8i
