# Thanks for your wonderful wiki contributions!

Over the past week, we have started merging several wiki pages together, so as to present a coherent picture which allows people to learn about a particular concept. After combining the existing writeups, we have also added in great problems that the community has written. This allows others to learn, read, practice and solve, all on one page!

Some pages that I would like to highlight are:
Completing the Square
Induction
Regular Polygons
Modular Arithemtic
Combinations
Newton’s Laws of Motion
Simple Circuits
