Best Answer

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

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.
