how do you add and subtract complex numbers?
479886
When you subtract complex numbers, you first need to distribute in the minus sign into the second complex number. Then, regroup the terms so like terms are next to each other. Combine those like terms, and you have the answer! Watch this tutorial to see a great example!

If you want to subtract something, you have to enter it as a negative number. Think of it as telling the machine you want to add into the total the number 6 you just entered, you want to add in the 5, take away or subtract the 9, and take away or subtract the 8.

To subtract binary numbers, simply align the 2 numbers and subtract as you would a regular problem. To subtract with the complement method, align the numbers and, if necessary, add zeros to the front of the second number to give it has an equal amount of digits.
