Tutorial

This tutorial will assist you in the process of learning how to contribute to the National Association of Math Circles Wiki.

Creating an Article

To create a new article, visit Submit Wiki Page. If the title of the article you are creating already exists, you will not be allowed to create that page and will see the error message "A page with this name already exists." with a link to that already existing page. You can then click on that link to edit the article.

If you click on a link to an article that does not exist, you have the option of creating that article.

Editing an Article

To edit a wiki page, click on the Edit button above the article while you are logged in. In the Body box, you will see any existing text written for the article, including the syntax. You may write around or replace the text to edit the article.

Wiki Syntax

Text

Here are a few common ways to format content in your article.

  • Bullets * - Use the asterick symbol (*) at the start of each line
  • Indent - Use the colon symbol (:)
  • Bold Text - Place three apostrophes directly before and after the word that is to be bolded (Example: '''bold word'''
  • Italic Text - Place two apostrophes directly before and after the word that is to be italicized (Example: ''italicized word''

Visit the Help page to learn more about formatting text.

Internal Links

To create a link to another article in the wiki, place two square brackets directly before and after a word that is the name of the article. For example, to create a link to the What is a Math Circle?, you would type [[What is a Math Circle?]]. Note, the name of the article is not case sensitive. So, [[What is a Math Circle?]] would be the same as [[what is a math circle?]] or [[WHAT IS A MATH Cicle?]].

If you need to make the title of the link a name that is different from the actual name of the article, you would type in this format: [[What is a Math Circle?|Learn About What is a Math Circle]]. This would display a link titled Learn About What is a Math Circle that will direct you to the page called What is a Math Circle?.

External Links

You use external links to link to a page that is outside of the National Association of Math Circles Wiki. You begin with one square bracket, the URL of the external link, a space, the text that should appear to be linked, and another closing square bracket. For example, to create a link to the MSRI webpage, you would type [http://www.msri.org MSRI].

HTML

You may use a limited amount of HTML when editing wiki articles. This includes:

<table> <tr> <td> <th>
<h1> <h2> <h3> <h4>
<h5> <h6> <center> <div>
<br> <strong> <em> <p>
<b> <i> <ul> <li>

Math

There are a few different ways to render Latek and math in your article.

To enclose inline math, use dollar signs.

For example: 

$x^2$
Renders:
$ x^2 $

To display paragraph math, enclose the math in between two dollar signs.

For example: 

$$x^2$$
Renders:

$$x^2$$

You may also enclose math in between two "equations" tags. For example, this syntax:

 <equations>
\int \ln(x) \;dx
&= \int 1 \cdot \ln(x) \;dx &= x \cdot \ln(x) - \int x \cdot \frac{1}{x} \;dx &= x \cdot \ln(x) - x
</equations>

Renders:

\begin{align*}<br /> \int \ln(x) \;dx<br /> &= \int 1 \cdot \ln(x) \;dx &= x \cdot \ln(x) - \int x \cdot \frac{1}{x} \;dx &= x \cdot \ln(x) - x<br /> \end{align*}

Other examples:

1) 

$\sum_{k=1}^\infty \frac{1}{k}$
2) 

$!\sum_{k=1}^\infty \frac{1}{k}$
Renders:
1)
$ \sum_{k=1}^\infty \frac{1}{k} $
2)
$\displaystyle \sum_{k=1}^\infty \frac{1}{k} $

To make a dollar sign, you have to type: 

\$
