Math is hard

2 + 2 = 4

Trivia Question: What is the longest path for the theorem 2 + 2 = 4?

Trivia Answer: A longest path back to an axiom from 2 + 2 = 4 is 150 layers deep! By following it you will encounter a broad range of interesting and important set theory results along the way. You can follow them by drilling down this path. Or you can start at the bottom and work your way up, watching mathematics unfold from its axioms.
