Other than that, it's simple ideas we all know are true, but if you think about it, these are the only things you need to know to prove 1+1=2.

2013年1月15日 · The work of G. Peano shows that it's not hard to produce a useful set of axioms that can prove 1+1=2 much more easily than Whitehead and Russell do. The later theorem alluded to, that $1+1=2$, appears in section $\ast110$:

2022年7月27日 · Discover the fascinating story behind how Principia Mathematica took 300 pages to prove that 1 + 1 = 2, a mind-boggling proof by Bertrand Russell and Alfred Whitehead.

2023年5月25日 · $1 + 1 = 2$ where: $1 := \map s 0$ $2 := \map s 1 = \map s {\map s 0}$ $+$ denotes addition $=$ denotes equality $\map s n$ denotes the successor mapping. Proof 1. $1$ is defined by hypothesis as $\map s 0$ and $2$ as $\map s {\map s 0}$. Hence the statement to be proven becomes: $\map s 0 + \map s 0 = \map s {\map s 0}$ Thus:
