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.
