You are simply an amazing mathematician. In fact, do you consider yourself a mathematician or just a retired math teacher? Is 32 correct? I say yes.

just a retired math teacher A Mathematician is anybody who has a deep love for mathematics. He is one who can leave eating, drinking, etc. for his love. Well, I see my self here too 32 is correct

To me, you are a mathematical genius. There is no problem that you can't solve. . .thus far anyway. How do we get more people to join this site? I recently joined a Lehman College FB group. I am sure there are students there yearning for math help. I will introduce this site there and hopefully more students (and perhaps staff as well) will start posting and participating here.
