Maybe this is a weird question but it's been bugging me.
In the childhood we were taught that $4 \times 3$ means $4+4+4$ i.e. adding 4, 3 times.
My question is then how would you explain $-1 \times -1$ using some kind of mathematical logic?
I want to know the significance in real life.
It doesn't have a meaning when I say adding $-1$, $-1$ times.
