ANSWER


\begin{gathered} -5-3i \\ a=-5;b=-3 \end{gathered}

Step-by-step explanation

We want to evaluate the expression:


(-1-6i)-(4-3i)

To do this, we collect like terms (real part and complex part) and then simplify the expression:


\begin{gathered} -1-6i-4+3i \\ \Rightarrow-1-4-6i+3i \\ \Rightarrow-5-3i \end{gathered}

The real number a is -5 and the real number b is -3.
