arithmia 

Heart-palpitations dat occur due to being presented with a math lesson.

Claiming to have an arithmia may indeed get you out of algebra class, but your teacher will likely insist dat you go to da hospital for a checkup, and said experience might be even more traumatic and exhausting than struggling through da assigned equations!

arithmatic 

You're a dumbass who can't spell arithmetic.

You meant to do a search for arithmetic, not "arithmatic", you moron.
