OG? No? ok.
If you find maths hard DON'T LOOK AT THIS!
- We start off by defining the natural numbers (ie positive integers) in terms of sets.
- For any set S, define a "successor" function f as f(S) = {S, {S}}
- Then we define the natural integers as such: Define the number 0 to be the empty set, which I'll write here as O.
- Then each successive integer (ie "n+1") is just the preceding integer put through the successor function, example:
