Lunar Arithmetic Concepts and Operations

The video introduces lunar arithmetic, a system where addition and multiplication rules differ from traditional arithmetic. In lunar arithmetic, the larger digit is chosen for addition, and the smaller for multiplication. The video explores lunar squares and primes, explaining how primes are defined differently on the moon. It concludes with a proof that there are infinitely many lunar primes.
