    Your solution for 51 doesn't appear to be valid.

      Thank you for pointing this out.😃 #51 should be (4!-4+.4)/.4

      ​​​@@LearnPlaySolveFor the operations you're allowing, ending at 100 may be stopping just in time, as I don't think 103 is possible. The problem is that 7 can't be done with two 4s, so you can't get the 103 by making 96 with two 4s (i.e. 4! × 4), then using the two remaining 4s to add 7. Is there a way to do 103 without introducing a new operation?

      Thank you for your question. The solution I discovered for 103 is: 44/.4(repeating) + 4.
      That's not to say there aren't other solutions. I might do another video in the future showing solutions 101-200.

      @@LearnPlaySolve Hmm, okay. So you're allowing concatenation. None of your solutions for the numbers up to 100 utilized that.

      That's a good point. That's the only solution I've come up with. If you find one, I'd like to know.

    Challenge. Write each number with 3 sixes. Allowed mathematical operations are (+,-,/,*,(,),^, ln, √).
    I solved this problem as a student 52 years ago. It is known that then a six was the golden student grade.
    0=(√6-√6)/√6 1=((6-6)/6)! 2=(ln(6) + ln(6))/ln(6) et cetera.😎

      The only way I know how to get repeating 4s on an ipad calculator is by dividing it by 9. If you want 2 digits to repeat, divide it by 99. And so on.
