when both numbers are negative then you should `add` but keep the negative sign example `-2-3=-5` when you have two numbers one is positive and one is negative then ~if bigger number is negative answer would be negative (subtract) `-3+2==-1` ~if bigger number is positive then answer would be positive `3-2=1`
