-Two column geometry proofs (those of you who read this will think I am nuts, but it is like putting a puzzle together and it so amazing to see how the pieces fit together. So much fun!)
-Arithmetic in different bases - I did some of this when I was young, but not enough to really learn and understand it. I really understand how it all works now and how it all ties into our common bse 10 system. I can even handle base 12 and hexadecimal. Subtracting, adding, multiplying, "carrying", "borrowing". I love it all!
-Factoring Trinomials- A couple of years ago I learned a very cool method that eliminated the guess and check system that I learned and used for factoring as a high school student. It always works! It has been fun to share that with others and to just enjoy a part of math that I have loved for many, many years.
I am grateful for the opportunity to help people with math and look forward to the fun that next semester will bring!
