Stile supports mathematical notation, from simple super and subscript to full-blown matrices and calculus.

**Equations in your question text**

To insert equations into question text, simply click on the little **square root **icon within the text editor:

This brings up the **equation editor**. You can use any of the tools available in the equation editor toolbar to create your equation, fraction or other notation.

When you're finished, simply close it and it will be inserted as part of your question text.

**Equations in your Multiple Choice Questions**

This is where things get a little bit technical. Stile supports a mathematics computer language called **LaTeX** in most places where you can type, including in MCQ answers and automated feedback bubbles.

Using LaTeX, you can get fractions and other mathematical notation into MCQ answers.

So for example, this MCQ question in Stile...

...actually looks like this when you click the *Edit* button:

From the above example, if you wanted to display the fraction , you would type:

**\frac{10}{15}**

The **\frac{numerator}{denominator}** tells Stile to display a fraction.

**\frac** is a part of the LaTeX language, which allows you to create complex representations.

**Subscript and superscript**

To get an expression *exp* to appear as a subscript, you just type **_{exp}**

To get *exp* to appear as a superscript, type **^{exp}**

LaTeX handles superscripted superscripts and all of that stuff in the natural way. It even does the right thing when something has both a subscript and a superscript.

A few other useful ones are:

- ≈ \approx
- \approxeq
- \geq
- \leq

For more symbols and further reading, this guide is a good introduction.

If you're doing really advanced stuff, this is the complete 300-page list of all symbols.

**Too hard?**

There is also a nifty little equation editor here that you can use to build your equation, then paste the code it gives you into Stile (this GIF may take while to load properly):

So for Pythagoras' theorem, HostMath spits out **a^{2}+b^{2} = c^{2}**

You can then copy and paste this into the other boxes and simply change the variables etc in the LaTeX:

**Still too hard? Use Unicode!**

Unicode is an international standard for encoding common characters. This Wikipedia article has a lot of handy superscript and subscript characters which you can just copy and paste into any place in Stile - or just grab them here:

**Superscript **

x⁰ x¹ x² x³ x⁴ x⁴ x⁵ x⁶ x⁷ x⁸ x⁹ xⁿ

**Subscript**

x₀ x₁ x₂ x₃ x₄ x₅ x₆ x₇ x₈ x₉ xₒ xₓ

You can even do some common **fractions** with Unicode:

¼ ½ ¾ ⅔ ⅙ etc

(see this article for a more complete list)

However, if you want something more complex, you'd have to use LaTeX.
