I'll do you one better. Just using "4" as an example, I understand that 0 x 4 = 0, but 4 x 0 should equal 4. If you have nothing and you increase it by nothing 4 times, that's still nothing....but if you have 4 and you increase it by nothing, don't you still have the original 4???
You mean if I take 7 games from 4 of my friend I can have 82 games and if I take 7 games from my 2 friends I can have 41 games and if I take 7 games from my 1 friend I will have 7 games . Well that's strange!!
