@crusader7257: Graham's number is an insanely huge number used in a real math proof by Ronald Graham. It's so big that: you could never write all its digits, the observable universe doesn't have enough atoms to store them, and even huge numbers like a googolplex are tiny compared to it. The weird part is how it's built. Instead of normal exponents, it uses repeated "up arrows": Then: Then more arrows make numbers explode insanely fast. Graham's number starts with: Then the NEXT number uses ® itself as the number of arrows. After repeating this process 64 times, you get Graham's number. Important: it's finite, it's an exact number, but it's way beyond anything humans can visualize. Also, it's not the biggest number in math #fyp
