In what sense is subtraction the reverse of addition and division the reverse of multiplication?

Re: Terminolgy

Think of a number, then add something to it. Subtract the number you added, and you get back to the original number.

Same goes for multiplying then dividing.


Why did the vector cross the road?
It wanted to be normal.
