You can add or subtract complex numbers by treating the i as a variable and combining like terms.
I am having a lot of trouble figuring out these equations with imaginary numbers.
1. (3+2i)+(7i)=
2.(16i)+(2i)=
3. (2+i)(3+i)=
4.(4+i)(2i)=
Can someone please walk me through how to do these problems? Thanks.
(3+2i)+(7i)=
3 + 2i + 7i=
3 + 7 + 2i  i =
10 + i
