  Man, calculators with fraction support weren’t all that common when I was in school.

    Now imagine having a calculator with symbolic math support and the ability to solve derivatives and integrals with unknown variables. And I took that shit into the SAT because the TI Inspire CX CAS was allowed. (Apparently that changed just this year holy moly)

    This post is how I learned they exist.

  look for ≈ on your calculator, try 22/7, the answer may surprise you

    Probably my favorite approximation of pi. With four symbols, you have like 18 digits.

      Do you, though? Pi starts 3.141592, but 7/22 starts 3.142857, already wrong by the 4th digit.

  Decided to try this by hand just for the fun of it. I stopped at twelve decimal points because it seems to just go on forever and I can’t do this all day. 2.571428571428…

    Yeah, n/7 does that. It’s a loop of 142857, and changing the numerator shifts where in the loop it starts.

    They also go in a pattern where the ‘loop’ starts with the Nth largest number in the sequence. So:

    1/7= .142857 repeat 2/7= .285714… 3/7= .428571… 4/7= .571428… 5/7= .714285… 6/7=.857142…

  If you want a rounded answer, press the rounded answer symbol. If you press the exact answer symbol, the calculator will give you an exact answer. It can’t guess what you want, you have to tell it.

  but there’s a more important math question,

  with heavy and deep philosophical implications…

  Actually it makes sense to calculate “analytically” as long as possible and only after that doesn’t help anymore, go to “numerical” calculations.
