Okay I'm Performing Operations with Complex Numbers and its prety confusing to me I have this equation and its somthin to have to do with imaginary numbers my equation is (6-3i) + (5+4i)

1) (6-3i) + (5+4i)

2) 6 - 3i + 5 + 4i

3) 4i -3i = -6 - 5

4) I = -11

Uh... do you mean: (6-3i) = (5+4i)?

Because an equation has to have an equal sign, which I don't see in your question. What you gave is called an expression. Anyway, if it's like you said, then that's what you have to do:

(6-3i) + (5+4i) = 6-3i + 5+4i = 11 + i

And that's all. 11 is the real part, and i is the imaginary part.

rolcam:

I = sqrt(-1); a mathematical concept. Electrical Engineers use j rather than I to represent the same concept.

5+3i is an example of the rectangular form of a complex number. 155 @ an angle of 90 deg is the polar form/
Usually the "@ an angle" is written as a symbol that looks like a < sign laying on it's bottom side.

Or we use the trig form like

r(cos\theta + isin\theta) or in Euler's form re^{i\theta}

if my memory is good. Arg, I have to revise!! :(
