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.

To find the real part of the difference, subtract the real parts.

To find the imaginary part of the sum, add the imaginary parts.

To find the imaginary part of the difference, subtract the imaginary parts.

ExampleSuppose 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 expressionsYou've probably done things like (4-7x) + (-6+x). In that case, just pretend i is x when you're doing these problems. (It works for multiplying too, except that when you get an i2 term you should substitute i2 = -1 )Q: How to add and subtract complex numbers?

By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract

You add all the numbers with + signs and subtract all that have minus signs.

You can always do that.

just change the fration with the smallest denominator and add or subtract the way you always do.

you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..

you add the numbers together than divide that by 2, after that you add how many numbers there are then subtract 2

If both numbers are positive, simply add them as you learned in 4th grade. If both numbers are negative,simply add them but add a minus to the answer. If one is positive and the other negative, ignoring the signs,subtract the smaller from the larger and add the sign of the larger to your answer.
