Furthermore many of the other ponies my age are having a hard time doing it. For a human even if a kid struggles with math, they would still be better by this age. I don't think ponies are dumber or something like that, as far as I've seen in all other aspects, they are comparable to humans although smaller. So it's really just math that seems to be a difficulty for them, my theory is that a pony's mind is less geared towards math than a human's although I don't know the reason, I just can't see another possibility.
