Answer
To subtract two complex numbers, we subtract the real parts separately and then subtract the imaginary parts separately.
Work Step by Step
A complex number consists of a real part and an imaginary part. To subtract two complex numbers, we subtract the real parts separately and then subtract the imaginary parts separately. For example:
\begin{equation}
\begin{aligned}
(5+7i)-(2+3i)&=(5-2)+(7-3)i \\
&=3+4i\\
\end{aligned}
\end{equation}
