Wooclap allows you to insert mathematical formulas in a question and its possible answers by using the AsciiMath and LaTeX formats.

**Note : **These formats are not supported in the answers of *Matching* questions. These answers are displayed on students' phones as drop-down lists, the design of which we can't control. We are currently looking for a way to work around that limitation.

**AsciiMath**

Simply surround formulas by backticks ` or by the elements <math> and </math>.

Examples:

`<math>1/(x+1)</math>`

or

`1/(x+1)`

`<math>text(N)_2 + 3 text(H)_2 -> 2 text(NH)_3</math>`

or

`text(N)_2 + 3 text(H)_2 -> 2 text(NH)_3`

`<math>sum_(i=1)^n i^3=((n(n+1))/2)^2</math>`

or

`sum_(i=1)^n i^3=((n(n+1))/2)^2`

You will find a summary of the available symbols here.

**LaTeX**

Examples:

`$\frac{1}{x+1}$`

`$e^{i \pi} + 1 = 0$`

`$\oiint_{\partial \Omega} \mathbf{E}\cdot\mathrm{d}\mathbf{S} = \frac{1}{\varepsilon_0} \iiint_\Omega \rho \,\mathrm{d}V$`

The formulas are rendered using the KaTeX engine. The list of supported functions is available here: https://katex.org/docs/supported.html.

N.B. If you wish to use the dollar sign in your question, here is how you can obtain it, without messing up your LaTeX format.

` $$ 500 or \$ 500`
