Follow these simple steps to add an example:

  1. Look over one of the wikis listed below, taking note of the page organization.
  2. Think of a question that could help someone understand how to solve problems related to the wiki topic. It is especially helpful if you can add to a section of the wiki that is missing relevant examples.
  3. Post your example and a solution! You can add an example using the following syntax:
###Example Question. This is the question.


This is the answer to the question, with a detailed solution.

I'm going to contribute to "Simplifying Radicals". Can I add something related to higher mathematics, which is excluded from Olympiad topics? Swapnil Das · 1 year ago

@Swapnil Das Certainly. We will sort them into the corresponding levels, so if the problem is really hard it will be used in the Level 3/4/5 set, as opposed to the Level 1/2 set. Calvin Lin Staff · 1 year ago
