There are no odd numbers divisible by 2

All odd numbers are divisible by 2.

You just get a decimal in the quotient.

1. Try again.

So there are infinite prime numbers, there exists only one even prime number, the odds of an prime number beeing odd is 100% ((∞-1)/∞)=100%) 2 is an prime number, therefore 2 is odd and is divisble by itself aka 2. Q.e.d.

Numbers is fake

(±sqrt(81) + 3)/6 is both odd and divisible by 2

So.

There are no even numbers divisible by zero.

By god they are right, this might change the future of mathematics!
