Fast way to write down math on a computer I am currently having the issue that I need to write down some mathemtaical equations that contains more complex items like matrixes and fractions rather quickly.
While LaTeX is the standard when typesetting math, I would like to know, if there is any simpler format for writing down stuff quickly?
(This is my first post here, so if this is off-topic, I can just remove the question)
 A: There are a number of tools that have been produced for formatting mathematics. Personally, I found Overleaf very easy to use and it converts the code you write into PDF in a few moments. Take a look at the following link https://www.overleaf.com/user/bonus
A: LaTex is really the best in my opinion. The trick is to save typing time. I installed Autohotkey. It has a simple script language, can be switched on and off, and allows the programming of keys. E.g. \ begin{bmatrix} \ end{bmatrix} (without the blanks) is Alt+M on my keyboard, \ subseteq is Ctrl+U or \ left. \ dfrac{d}{d}\ right|_{} is Alt+U. Just make sure not to overwrite keys you need for the standard purposes like e.g. Ctrl+C/A/V/X/Z.
Typical commands are
!n::
Send, {{}{}}{Left}{Left}
Return
^n::
Send, {{}{}}{Left}
Return
They produce {} and \ {\ } (without the blanks, but with the cursor positioned in the middle). My keyboard is full of shortcuts. They work so well, that I even use a TeX editor as a substitution for handwriting. I even managed to program that the accidental caps lock and num lock activation doesn't happen.
