    God I hated questions like this in school. There’s always something specific the teacher is looking for, but nothing to point you towards it.

      Yeah, I always felt like I was either pointlessly restating the obvious or it expected me to derive the damn thing from first principles.

      AI slop proof, just because I was curious if duck.ai could do it

      Using the natural numbers defined from 0 by the successor operation S:

      1=S(0), 2=S(1), … , 20=S20(0), 40=S40(0)

      Define a < b to mean that there exists a natural number k such that

      a+k=b.

      Take a=20 and k=20. By repeated addition,

      20+20=40.

      Since 20 is a natural number, there exists a natural number k such that

      20+k=40.

      Therefore, by the definition of the ordering relation,

      20<40.

      (Is it correct? Fuck if I know!)

      I’m thinking maybe “Because if you subtract 40 from my number you get a negative number,” but I could be either over- or under-thinking it.

      Usually the pointer is the blahblah the teacher was droning while you were fantasizing about the attractive classmate sitting directly in front of you
