Complex numbers All questions and Show your work

I’m not going to do it for you but i can explain that you just need to do it like normal 1st degree function. it’s structure is (a+bi) where a & b are numbers and i^2 = -1

Ex: the 1st one structure is (a+bi)+(a-bi) so u just need to add a+a and (b+b)i

M< 5 = 80 , < 2 = 80, < 6= 100, < 3= 100, < 7= 80, < 4= 80, < 8= 100
