# Help others by adding examples

Want to contribute and make Brilliant’s wikis more awesome? Have ideas for examples which could illuminate one or more of the topics below? Contribute some examples now!

We’ll be providing feedback on these contributions, so this is a great opportunity to improve your mathematical writing skills while making your mark on Brilliant. If you get stuck, come chat with us.

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:
 1 2 3 4 5 6 7 8 [[start-example]] ###Example Question. This is the question. ------- This is the answer to the question, with a detailed solution. Please explain your steps so that people can follow along. [[end-example]] 

That produces output that looks like this:

Protip: As you’re editing, you can add relevant links to related wikis.

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

- 2 years, 6 months ago

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.

Can you add my wiki to the Algebra topics , so that wiki could get more examples.
