Honestly there's not much to prove
Axioms of real numbers states that addition and multiplication are commutative
so a+b=b+a and ab=ba for all a,b real
also 1 is the identity of multiplication so by the axiom 1(2)=(2)(1)=2
prove 1+2=3 depends how much you can assume on the real number system
hell this is more like a philosophical question than an analysis question -,- |
