I have always thought they should restest high school graduates at 36 years old. On the theory they had as much time to use what they learned as it took them to learn it, and the things they failed at would be the things they never needed, and forgot.
I actually used algebra in electronics tech school. by the time we reached the limits of my knowledge all of the students that would fail because they could not do the math were gone. After that, we never did math again. I concluded that the math was a filter to reduce the number of potential graduates.
I used trig when I was learning how to program computers and fly airplanes. I wrote a program to calculate a vector when dealing with crosswinds. never used trig again.
I have never seen a quadratic equation in the real world, never known anyone who ever worked one out of math class, and would not recognize one if I saw it running around. Still waiting for an explanation for why that was necessary.
