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
