It always bugged my that those two are supposed to be the smartest characters, yet they have them doing simple geometry problems, the kind i was doing in my first year of high school. If the artists really wanted it to be realistic, they could have had them doing some basic differential calculus, which is a bit more realistic for their grade level. Most likely the artists were the kind of retards who went straight from high school to art school, so they never saw math more complicated than trigonometry.
