get good.

It's also the answer to 21356772^2 + 24452313^3 = c^2

Then dividing the answer into the three pieces.

Take one of those pieces, divide by Pi

Then with that answer use it as the denominator while the numerator being the answer to length arc AB which is unknown, the outer edge being 210 degrees and the Radius being 18.

Now, with these two values, divide by Pi^3 and multiply them by 2.

Now take each even number and make it a 0 and each odd number and make it a one.

decode the binary, take the letters, and unscramble them into a 17 letter acronym which consists of complex wording and theorems.

That acronym is the password to the board
