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)+(7-i)=

2.(1-6i)+(2-i)=

3. (2+i)-(3+i)=

4.(4+i)-(2-i)=

Can someone please walk me through how to do these problems? Thanks.

(3+2i)+(7-i)=

3 + 2i + 7-i=

3 + 7 + 2i - i =

10 + i
