Always a happy day for me when my daughter's end of year math test has come and gone. I'm the world's worst math teacher ("It's as plain as the nose on your face that the answer is 12π") and she's not the most enthusiastic pupil ("I'm never going to use this anyway"). Can make for some tense moments.
On the upside I'm relearning all the things I've forgotten. It's not everyday that I have to calculate the volume of space in a rectangular box not occupied by three snugly fitting spheres. Or even the slope of a line and its perpendicular. Great fun.
