It's possible to write mathematics in several ways:

1. TeX

2. MathML

3. ASCIIMathML

We will go over them one-by-one.

Are you not familiar with any of these languages? Don't worry, you can use our formula editor to input mathematics using our on-screen keyboard, and it will give you the code to input in a theory page automatically. To find our formula editor, click on the x² icon when editing a theory page, then select formula editor.

### TeX

The most common way to input mathematics is using LaTeX. For example, inputting

#\frac{9}{6}+\frac{1}{2}#

gives:

Remember to put your code in between #'s for formatting purposes.

MathML

MathML is inputted in the source code of a theory page. You can access the source code by clicking on the </> button in the toolbar above.

For example, inputting

<math xmlns="http://www.w3.org/1998/Math/MathML">  <mstyle displaystyle="true" scriptlevel="0">    <mrow>      <mfrac>        <mn>9</mn>        <mn>6</mn>      </mfrac>      <mo>+</mo>      <mfrac>        <mn>1</mn>        <mn>2</mn>      </mfrac>    </mrow>  </mstyle>[/itex]

gives:

ASCIIMathML

MathML is inputted in the source code of a theory page. You can access the source code by clicking on the </> button in the toolbar above.

For example, inputting

@(9/6) + (1/2)@

gives:
