Answer
$1+13i$
Work Step by Step
$\bf{\text{Solution Outline:}}$
To simplify the given expression, $
(-4+11i)+(-2-4i)+(7+6i)
,$ remove the grouping symbols first. Then combine the real numbers and combine the imaginary numbers
$\bf{\text{Solution Details:}}$
Removing the grouping symbols, the expression above is equivalent to
\begin{array}{l}\require{cancel}
-4+11i-2-4i+7+6i
.\end{array}
Combining the real numbers and combining the imaginary numbers result to
\begin{array}{l}\require{cancel}
(-4-2+7)+(11i-4i+6i)
\\\\=
1+13i
.\end{array}
