first of all i think you need to take basic english courses before you even think about mathematical concepts
secondly you didn't even argue why what I said was the "dumbist" you ever read. you just posted a bunch of ad hominems that has nothing to do with anything
thirdly you never told me how 1+1=2 is observable in the real world
you obviously aren't able to think for yourself and the only reason you believe 1+1=2 is because someone told you so
no wonder you aren't capable of wrapping your mind around abstract mathematical concepts that have been around since ancient Egypt
yes not because you can prove it.
