Yes, science man :) that's what I Googled before I posted my edits.
Unfortunately, their eyes will probably glaze over if I try to explain it to them, I was hoping for a literal algebraic equation even though the actual numbers are unbelievably gigantic.
Actually, though... Well, with some exponents you start with 4, square it and subtract 2, square that and subtract 2, square THAT and subtract 2...I think I can explain that adequately.
Hmmmm, might still be able to do this.
