• M0★ M1★ M2★ M3★ M4 M5

    Observations halfway through the video:

    I got 5, but from the fact that 50 reversed is 5, 50 - 5 = 45

    But anyways 5 was just like what Prof. Loh got

    Coincidence? I THINK NOT

    Also

    Prof. Loh's guess and check numbers

    74 - 47 = 27
    84 - 48 = 36
    92 - 29 = 63
    83 - 38 = 45

    All multiples of 9, and it seems that the higher number you start with, the higher your sum. It is just a general trend, of course, as you can see 84 - 48 was a lot lower than 83 - 38.

    But...

    Coincidence? I THINK NOT

    And as it turns out... I thought right

    Coincidence?
