Using algebra and a little deception, Mr. John Hush proves (or does he?) that 1 = 2 to a class of amazed calculus students.
15 Ιαν 2013 · 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 $\ast110$:
21 Αυγ 2021 · Proof that 1+1 = 2 【Fundamentals of Mathematics】. I think we've all had the question (at least once) on why 1+1=2. It's like asking the definition of 'the', and it's rather confusing on...
