We often receive questions from content creators about speeding up the process of creating content in Grasple. One practical way in creating content more efficiently is by typing LaTeX code when composing exercises and questions. In this article, some tips and tricks are presented as well as an overview of all LaTeX code that is used in Grasple. 

Grasple makes use of the mark-up language LaTeX in order to visually display mathematical notation. The buttons around the answer box are essentially shortcuts for LaTeX code, but it is possible to write out these codes manually. It might seem like a tedious task to learn to write out exercises and questions using LaTeX, but it can definitely accelerate the process of creating content

LaTeX codes can in some instances be readily found on your keyboard. For example, the LaTeX code for the division symbol is simply a forward slash ( / ). However, in most instances codes are prefixed by a backslash ( \ ).

There's a notable difference between writing LaTeX code in the answer box and in text (as is visually displayed in the GIFs below). 

In the answer box, LaTeX code is instantly displayed.  

In normal text, you need to enclose your LaTeX command between a backwards slash and open parenthesis \( on the left side and a backwards slash and closing parenthesis \) on the right side. Your commands are displayed once you click on preview.

Alternatively (in normal text), you can click on the formula editor on the left hand side and type LaTeX code without having to enclose your command between \( and \). Symbols are also instantly displayed.

Below, you can find an overview of all codes that are used in the buttons around the answer box starting from the top left going right.
