I do not use hard math like the Pythagoriam Symptom, in my figurings, so I don’t teach using hard math.  and the students say, it’s so simple, look all you have to do is: and then the stacking of the letters and numbers and the dog house with the awning, and I have to go six problems back just to get one wall of a long-forgotten labyrinth when I can already see the thing made out of hollow pipe and stretchy fabric.
