1. (5 - 2i) + (-8 + 6i)
Steps
=(5 - 8) + (-2 + 6)i
= -3 + 4i

2. (-2 - 2i) - (8i) + 6
Steps
Remove parentheses:
= -2 - 2i - 8i + 6
Add similar elements: -2i - 8i = -10i
= -2 - 10i + 6
Add/subtract the numbers: -2 + 6 = 4
= 4 - 10i

3. ((4i) + (6i) + 6 + 2i)
Steps
Remove parentheses:
= 4i + 6i + 6 + 2i
Group like terms
= 4i + 6i + 2i + 6
Add similar elements: 4i + 6i + 2i = 12i
= 12i + 6

Well i haven't learned this yet but ill give it a go. So i used PEMDAS.

1. (5-2i)+(-8+6i)= (5-8)+(-2+6i)= 3+4i

2. (-2-2i)-(8i)+6= (-2+6)-(-2-8i)= 4-(-10i)

3. (4i)+(6i)×6+2i)= (10i+6+2i)= 12i+6
