I believe that lots of people really can't do math. Most people are fine until fractions. Many people never gain any intuitive feel for what "2/5 * 7/8" even means. It only gets worse with algebra. They can often learn the mechanics of fraction arithmetic and solving equations, but they will never understand how to apply the knowledge later in life.
