"Look at this cool new tool we invented for understanding math, and grades are improved greatly :)"

"No fuck you that's the wrong way to do numbers! Won't anyone think of the times tables? :rage-cry:"

    Timmy, you know you can't eat your pudding until you do the xor trick on one more pair of 32-bit words followed by a one's complement subtraction!

      you've already mastered long division I don't see why you're having so much trouble with this. if you did your homework every day you wouldn't have to study so hard for the test!
