Question

write the expression as a complex number in standard form identify the real and imaginary parts (-11+3i)+(4-6i)

Answer 1

When adding complex number of the form:
\[a+b\iota\] you need to add up the real and imaginary components separately.

In this case we have:
\[(-11+3\iota)+(4-6\iota)=-7-3\iota\] i,e,:
\[-11+4=-7\] and \[3-6=-3\]

Then we can identify the real and imaginary parts.
