Question

Write a paragraph proof that 1+1=2 (Fun fact: it took over 72 pages just to prove that 1+1=2)

Answer 1

basically with no further elaboration ever since k-g 1+1 have always been 2 ; - ;

Answer 2

Answer:

The theorem here is essentially that

if a and 3 are disjoint sets with

exactly one element each, then their

union has exactly two elements. ...

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.
