IMSUM(z1,z2,z3...)

This function gives the sum of the two or more complex numbers.
IMSUM(z1,z2,...), where $z1,z2,...$ are the complex number is of the form $a+ib$ .
where $a$ & $b$ are the real numbers. $i$ is the imaginary unit . $i={\sqrt {-1}}$ .
In this function $z1$ is required. $z2,z3...$ are optional.
Let $z1=a+ib$ and $z2=c+id$ .
The addition of two complex number is: $(a+ib)+(c+id)=(a+c)+(b+d)i$ where $a,b,c$ and $d$ are real numbers.
We can use COMPLEX function to convert real and imaginary number in to a complex number.

IMSUM("12+10i","8+16i")=20+26i
IMSUM("-7-12i","-10-4i")=-17-16i
IMSUM("-14i","10-4i")=10-18i
IMSUM("17","24+12i")=41+12i
IMSUM("12+10i","8+16i","5+2i")=25+28i
