How to Add and Subtract Positive and Negative Numbers Numbers Can be Positive or Negative. This is the Number Line: Negative Numbers (−) Positive Numbers (+) "−" is the negative sign. "+" is the positive sign : No Sign Means Positive. If a number has no sign it usually means that it is a positive number. Example: 5 is really +5. Balloons and Weights . Let us think about numbers as balloons

**Adding and Subtracting Complex Numbers**

To find the imaginary part of the sum, add the imaginary parts. To find the imaginary part of the difference, subtract the imaginary parts. Example Suppose you want to add the following complex numbers: 3-2i and -7-6i. The real part is 3-7, which is -4. The imaginary part is -2i+(-6i), which is -8i (because -2+(-6)=-8). So the answer is -4-8i. It's just like adding expressions You've probably... How To: Add and subtract complex numbers By WonderHowTo; 10/12/08 2:40 PM. WonderHowTo.

- Take a look at how we can add and subtract complex numbers and look at their imaginary and real parts. Practice the concept with our guided example questions.
- (Add (subtract) the real parts, add (subtract) the imaginary parts.) If you have to multiply (divide) complex numbers, it is easiest to do it using the polar coordinate representation: If z 1 = (A 1 ,θ 1 ) = A 1 e iθ1 and z 2 = (A 2 ,θ 2 ) = A 2 e iθ2 , then
- Handle the real parts and the imaginary parts separately. Don't try to borrow ("regroup") or carry. It can't be done. To find the real part of the sum, add the real parts.
