Explain how complex numbers combine algebraically and graphically (solely using the graph, meaning just graphing the result of the algebraic computation is not sufficient) under the following operations:
complex number is written as x+iy
lets consider 2 complex numbers x1+iy1 and x2+iy2
simply adding (x,y) coordinates gives new complex number
now for graphing we will consider polar coordinates
consider 2 complex number
multiplying two gives a new complex number
graphing is simple u have to plot numbers before addition and after addition.
for multiplying draw a line with angle (@1+@2) and radius r1*r2
