Answer
To add two complex numbers, we add the real parts separately and then add the imaginary parts.
Work Step by Step
A complex number consists of a real part and an imaginary part. To add two complex numbers, we add the real parts separately and then add the imaginary parts. For example:
\begin{equation}
\begin{aligned}
(2+i)+(5+7i)&=(2+5)+(1+7)i \\
&=7+8i\\
\end{aligned}
\end{equation}
