This flashcard is designed as a brief introduction into using $\LaTeX$ with SASENSEI. With LaTeX you can introduce functional mathematical formulae into your questions and explanations. Note: At present SASENSEI does not support the use of LaTeX in your answer options.

Firstly a simple introduction. To use $\LaTeX$ with SASSENSAI you make use of the dollar ($) symbol.

• Use one leading and one trailing dollar will produce an 'inline expression'. e.g. $\LaTeX$
• Using two leading and two trailing dollar signs will produce a 'displayed formula'. e.g $$\LaTeX$$

For a summary of $\LaTeX$ the followings URLS may be useful: $\LaTeX Symbols Summary$ The Comprehensive $\LaTeX$ Symbol List
