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.

Adding a negative number is just the same as subtracting a positive number. So 3 plus (-4) is the same as 3 minus 4. The answer to 3 - 4 is the inverse of the answer to 4 - 3 So if 4-3=1 then 3-4=-1 Other useful rules: Taking away a minus number is the same as adding a plus number. Subtracting a plus number, or adding a minus number, is the same as taking away a positive number.
