the opposite of 3; 5 times = 3 3 3 3 3 = 15 so the opposite of 5 times gets you to 15

Do you understand / accept (1)*(1) = 1 ?

So then you get \[0 = 0\cdot 0 = (aa)\cdot(bb) = (a+(a))\cdot(b+(b))\]so using distributivity\[ = a\cdot b + a\cdot (b) + (a)\cdot b + (a)\cdot(b) = a\cdot b  a\cdot b  a\cdot b + (a)\cdot (b)\]thus altogether \[ 0= (a)\cdot(b)  a\cdot b\] and that means nothing else than \[(a)\cdot(b) = a\cdot b\]

hehe, Mathematics needs it, or from a certain point on anything will be arbitrary because you can't tell intuitively what's true and what's false.
