It's really hard to explain, but, using math can you prove it? This guy apparently thinks it's wrong: http://www.timecube.com but he's insane anyway, so who cares.
The question asked is, "If positive one times positive one equals positve one, then why does negative one plus negative one equal positve one?"
The math he tries to prove it with is this:
-9 + -9 + -9 + -9 + -9 + -9 + -9 + -9 + -9 = -81
Do you see the flaw he made? there are a positive number of negative nine there, and it was multiplied by a negative number, so you must subtract -9 a bunch of times:
-9 - -9 - -9 - -9 - -9 - -9 - -9 - -9 - -9 = +63
But that's still wrong, and do you know why?
Because you always start with 0
here's the positive again:
+9 x +9 = +81
0 + +9 + +9 + +9 + +9 + +9 + +9 + +9 + +9 + +9 = +81
so,
what's the math then that proves this?
