Quick summary: negative sign replaces addition with subtraction and vice versa. For example, adding a -5 is the same as subtracting +5. When multiplying or dividing signed numbers, remember that two minus signs in multiplication cancel out. If you have two minuses, the result is +, for three minuses the result is - because the first two cancel out and the third one remains.
