  I’ll add Spanish! “Alfil”, taken from arabic “(al-)fil”, taken from persian “pil”, meaning “the elephant”, since at some point in the past the piece was, evidently, an elephant.

  No, it’s correct. You define the operation by it’s properties. It’s not saying that “a plus 0 = a” but "the result of applying the binary operation ‘+’ to any number with 0 should give the original number."

  • is just a symbol. You could instead write it as +(a,0)=a and +(a,S(b))=S(+(a,b)).

  You have to have previously defined 1=S(0), 2=S(1), 3=S(2), and so on.

  The system works perfectly, it just looks wonky in base 10. In base 3 0.333… looks like 0.1, exactly 0.1

  Do you know what an irrational number is?

• ⁨Comment⁩ on ⁨I just cited myself.⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Sure, let’s do it in base 3. 3 in base 3 is 10, and 3^(-1) is 10^(-1), so:

  1/3 in base 10 = 1/10 in base 3 0.3… in base 10 = 0.1 in base 3

  Multiply by 3 on both sides:

  3 × 0.3… in base 10 = 10 × 0.1 in base 3 0.9… in base 10 = 1 in base 3.

  But 1 in base 3 is also 1 in base 10, so:

  0.9… in base 10 = 1 in base 10
