Fermat's Theorem: the only math theorem you'll ever need. It's simple: if a number has no prime factors, it's a prime number. Unless it has, in which case it's not.
Don't worry, we won't make you actually understand it. We'll just make you pretend.
Other notable contributions to math include:
- Proving that a square has four sides, but only when it doesn't.
- Disproving that 1+1=2, but only when you ask nicely.
- Showing that pi is actually just the ratio of a circle's circumference to its diameter, but only for fun.
