No... Let's say you have 1- (-1) you can take away the two negatives and make it a positive. So, 1-(-1) is equal to 1+1. make sense?
Yes, but in this context, we're talking about wrongs and rights. If you imagine a wrong is negative and a right is positive, then it would be (-1)+(-1)= -2, which is negative, therefore not a right.
In your example it was a right (positive) minus a wrong (negative), which doesn't make any sense, as you can't subtract a wrong.
I agree that the logic is wrong for sure you're deffinetly right about that. I'm just saying it's not only in multiplication. But I get where you're coming from
