If multiplication is just repeated addition, then why when 2 negatives get multiplied they become a positive?
In: Mathematics
Say you pay $2 for something. You do this twice, so you lose $4. This is -2*2=4.
But there was a mistake, it was supposed to be free! You’ve already lost your $2 (-2), but you’re going to get to undo those losses (-2). That’s -2*-2=4, so you get your $4 back.
