This game was made by the same person whose iconic game has you unironically adding five or six two-digit numbers together, in a row, five times, while being chased. (And a lot of people manage it, and it's still just arithmetic rather than any sort of advanced mathematics which you probably end up practicing 300 times before then.)
I think you should have a calculator on hand if you need to. You don't have to be undignified because of it. You can probably just put one on your computer if you don't want to take one out of somewhere. Otherwise you could check out other people playing the game
