I have to answer some questions about Steven Strogatz column
1. we should make a triangle game were we try to hula hoop in isosceles triangles, and then eat traingloe slices of cake.
2. calculus means a pebble used for counting, steven used rocks as examples in the article
3.you can add them up in pairs 1 and 10 2 and 9 etc. all pairs add up to 11 AND there are 5 pairs so they can can be multiplied to 55
