rules == axiomatic systems. So if you use the standard definition of addition in base 10.. 1+1=2 always, if it's a human invention, it can be otherwise somewhere sometimes even if you use the standard definition of addition in base 10. > > > Mathematical truth are independent of humans, life and the universe and the > rest, it's nonsense if it's otherwise. > > > What's "it's" in the above sentence? > It's, is the fact that mathematical truths are independent of humans.
