Yeah - I'm not mathematically inclined enough to understand what would be so funny about the 38x^3 denominator either?

Unless it's something that would cause an error due to memory/register size constraints, or cause the calculator to sit there forever on some of the other larger squares or test values due to 1986 speed of the ALU or whatever is in the calc?

My gut assumption is that it's some mathematics inside joke of some sort...

All of the other constants are expected. 1, 2, 9, 10 ok those make sense. Where does 38 come from? Ha ha. So random.

I could not have put it better myself.

    1 + 2 = 3
    3 * 9 = 27
    27 + 10 = 37
