That's not really true, there is a mathematical system where 0=1. It's just... Not very interesting, aside from it's existence.

- skissane 5y agoThat's not really true, there is a mathematical system (maybe even more than one) where "0=1", but when we say "1", we are not talking about what "1" refers to in such a system, we are talking about what "1" refers to in some mathematical system(s) in which "0≠1"
- throwawaymaths 5y agoNope. One is the multiplicative identity and zero is the additive identity. There's no a priori reason why the same number can't be both.
