There is (at least) one other solution, if anyone else wants to take a stab at it.
#followed by a character in Japt gives us the charcode of that character, so
#A=65, which the rest of the number then gets appended to, giving us
uis the modulo method (it differs from
%in that it will always return a positive number).
nmethod subtracts the number it is applied to from the number passed to it.
Gare the Japt constants for 11 & 15, respectively. So,
We now have
pmethod raises the number it's applied to (in this case that is, implicitly, the input integer
U) to the power of the number passed to it, giving us the 2 final formulas of
