# When adding a plus number with - number what do you get?

When you add a positive number and a negative number, it is the same as subtracting the negative number from the positive number. For example:

4 + (-5) is the same as 4 - 5 (which is -1).

One more example:

(-10) + 15 is the same as 15 + (-10) (because it doesn't matter what order you add numbers), which is the same as 15 - 10. (which is 5).

A bit more:

That depends on the value of the positive (plus) and the negative (-) numbers. For example, if you add a positive 5 with a negative 3 (-3), the answer will be a positive 2. But if you reverse it and add a negative 5 (-5) with a positive 3 (+3), the answer will be a -2. Wiki User
