# What is a negative minus a negative?

A negative minus a negative is equal to another negative number, a positive number or zero, depending upon the numbers in the equation. Subtracting a negative number from another negative number is the same thing as adding a positive number.

If the negative number being subtracted is the same as the number from which it is subtracted, the answer is zero. For example, -5 - (-5) = 0. If the negative number being subtracted is greater in value than the negative number from which it is being subtracted, the answer is negative. For example, -10 - (-8) = -2. If, however, the negative number being subtracted is less in value than the negative number from which it is being subtracted, the answer is a positive number. For example, -10 - (-12) = 2.
