What Are the Rules for Subtracting Integers?

Some simple rules for subtracting integers have to do with the negative sign. When two negative integers are subtracted, the result could be either a positive or a negative integer.

If -5 is subtracted from -9, the result is -4: (-9) – (-5) = -9 + 5 = -4. But if -9 is subtracted from -5, the result is 4, a positive integer: (-5) – (-9) = -5 + 9 = 4.

If a positive integer is subtracted from a negative integer, the result is a negative integer: (-9) – (5) = -14.

If a negative integer is subtracted from a positive integer, the result is a positive integer: 9 – (-5) = 9 + 5 = 14. If a positive integer is subtracted from a positive integer, it gives either a positive integer or a negative integer: 9 – 5 = 4 or 5 – 9 = -4.
