Math--either you got it or you dont. WRONG!!
Math is easily the most tested subject around. We have told genders and certain ethnic groups that they are more or less "apt" (aptitude) to learn and be good at math than others. Though I do believe we are born with a certain amount of innate mathematical ability, the rest is learned. No one comes out of the womb knowing calculus. Even the smartest geniuses had to learn it at some initial point. There may be other factors that contribute to how fast you pick up the concepts, but everyone can learn it.
Math can be very dry
As a math lover and teacher I can see why people say its dry. No emotion, lots of work, no colors, no laughter, no tears, either yes or no, one or two. This is what math looks like to many.
