Best ResponseYou've already chosen the best response.1So 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 \[(a)\cdot(b) = a\cdot b\]
