You have trouble adding 4+7+8+0+1 and seeing if that sum is divisible by 3?

The Rule for 3: A number is divisible by 3 if the sum of the digits is divisible by 3

They missed an opportunity with third test which would be slightly harder, but optional. You pass you get better buff you fail you die, but you can opt not to go for it.

Lol, you missed the point completely. Not going off of whether "I" can divide the number listed above or not I was giving an example. Place that example, or your HP number and put it in the equation of any problems it asks you to solve, Like Frizze said, knowing if its a prime or not. Further more, doing this in 10 seconds. If you wanna point fingers I'll admit, nope I can't do THAT in 10 seconds lol. I know I coullllld, but not in 10 seconds.
