Add the imaginary part together and the real part together
combine like terms
basic rule is\[(c+di)+(a+bi)= (a+c)+(b+d)i\]

ok i am lost
just combine like terms together like in this question you have \[(9 + 9.4i) + (-8.6 – 4i)= (9-8.6)+(9.4-4)i\]
ok so would you add the same ones together or would it be like 9 ^2
Add the real parts and add the imaginary parts. what is 9+-8.6?
you would add the same ones together
0.4
What is 9.4i -4i?
Yes. so the real part is .4
Now do the imaginary part
you just need to separate the real and the imaginary parts for real you have 9-8.6=0.4 for imaginary (9.4-4)i = 5.4i
9.4i-4i
So the answer is .4+5.4i
