- I'm a high-school math teacher completely frustrated with new math, reform math, fuzzy math, the color of math, talking about math, literacy across the curriculum and all those other things that get in the way of students actually learning math, not to mention the ever-present "You need to help raise our scores by taking one day a week to go over test-taking skills" and other administrative folderol. (He/Him/Mr.)
