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.
