If you want to get a sense of community participation in wikis, take a look at wiki collaboration graph.

Well, we're now in week 5 of the wiki weekend series. We've made hundreds of edits to wiki pages during these wiki parties and we've helped thousands of people learn about new math ideas! This week's theme: BASIC ALGEBRA.

Our goal this weekend is to fill out and improve some of our basic algebra pages, which will be a big help to those who are just getting started on Brilliant. To participate, feel free to jump in and write something helpful on one of the following pages. Note that unlike previous wiki parties, these pages aren't *empty*, but they are short and obviously cursory. They could use better explanations, better examples, etc. Please feel free to contribute however you'd like.

- Simple Equations
- Absolute Value Equations
- Absolute Value Inequalities
- Simplify Ratios
- Componendo and Dividendo

When you have made an edit that you are proud of, please make a comment and let us know, and thanks so much for your contributions.

TopNewestHey, I just got level 4 in algebra and I got a message asking me to edit a wiki for square roots. What do you guys think I should do?

I strongly encourage you to improve the wiki for square roots :)

The formatting system is unique on Brilliant. I saw different Formatting system on Expii. Can't we build a

Standard Formatting?Log in to reply

Yeah I want to do it but should I add more complex examples or something? This is my first time doing something like this so I don't want to screw up lol

If you think you can explain the concept better, then add a few lines of explanation.

If you can come up with useful explanations, add those.

If you can improve the existing write up and check for spelling / grammar / punctuation, do that.

I have added a definition and an example to Absolute Value Equations - Basic. I will be adding more soon.

I really feel like contributing some information!

But @Calvin Lin sir, can we use the information from other webpages which are very informative???

In general, you shouldn't use information from other websites. Thanks for asking!

Thank you sir!

The idea of the wiki is for it to be self contained, so try not to use information from other websites.
