Mathematical Bench Press

I experienced an amazing thing today. I sat in a Math class in which the instructor made the subject interesting. She obviously enjoys her chosen field and can get excited about how math has evolved. She also has a keen interest in the adult learners and the "aha" moments that occur. Today she taught about base 2,3,4 etc.
I was sitting in this class as a one on one support worker, (my new job as of yesterday). I was expecting it to be a bit dull, anticipating tomorrow when the schedule is recreation for 8 hours.
Now I'm looking forward to next week when perhaps our Math instructor will teach the tricks behind completing a **** Sudoku Puzzle. It bothers me that I struggle with these seemingly simple puzzles. If I compare it to weight training though, maybe I won't get as discouraged. I'm not lifting very much yet, but the more reps I do, the stronger I'll get, right?
