Math editor for super users
Guide on how to amplify your efficiency on the Abitti math editor, in ways the devs never even imagined...
The core of L'Math – the math editor – is based on the editor of the Finnish Abitti exam system. Still, a lot of people still use L'Math after upper secondary school. But how do you get a simple math editor to work for university algebra, quantum mechanics or anything that "lukio" had no clues about? This page contains tips for this particular use case!
TeX shortcuts
You can write TeX commands directly into the math box by typing a backslash and then the desired command. If you write a non-command, the written word becomes a text element, which is an excellent way of writing, for example, some of the more specific functions.
Various guides to learning TeX commands can be found online.
Combined and aligned formulae
A set of math formulas can be combined aligned by highlighting them and selecting "Combine and align" in the context menu. Similarly, the combined formulae can be uncombined from the context menu.
Number set shortcuts
The most commonly used number set markings can be quickly written using a backslash followed by the capital letter. For example, \Z + space produces the notation for integers, . Similarly, any letter can be changed to the bold font with the command \mathbb.
Parentheses and Bra-ket notation (\langle, \rangle)
L'Math uses the MathQuill library for math editing. If you want to type, for example, Bra-ket notation or algebra with unusual parentheses, you have to take into account MathQuill's tendency to require a closing bracket for the preview to work correctly. For example: for typing you first have to open the left angle bracket with \langle and then complete the right "bracket" by typing a vertical line |.
So, MathQuill allows for non-matching bracket pairs, but the preview does not work if you write them directly into the TeX code box (for example, only \langle without its counterpart).
