take 10 divide by two. you get 5. divide by 5... i THINK thats a prime but i could be wrong. you get one. neither show up in pairs of two so neither get "out" take them times each other.... equals ten. you get 5 times ten... it's fifty hmm, that's all i know.
DAMN! i see my error! Since its pythagorean theorum i was thinking it was 50 instead of 50 ^ 2 because of the squared root thing.
