LaTex for home use I would like to have a program similar to this website that allows me to write math equations.  Is there a good program that is easy to use.  I tried the LaTex add in for Google docs, but it is not that good.  It was simple to install, but I am not the excite about using it.  The output is inconsistent and blurry.  Is there anything else out there that is easy to use and has good output?  I was looking for something free.
I really would like to take notes on my computer for precalculus and calculus.  I'd like to be able to write equations in my notes.
 A: As Marty Cohen mentioned, the Markdown format is really handy!
I use an app called Obsidian- once you've downloaded it you can install a community plugin to have your notes sync automatically to a GitHub repo (you can keep it private). This way all of your notes are synced across your devices.
You can insert $LaTeX$ equations by surrounding your code in dollar symbols $/eqn$, and it renders live. CodeCogs offers a simple tool to generate equations using a GUI whose code you can then copy/paste into the Markdown file.
I hope this helps!
A: If you are on a Mac,
MacDown is great
(IMHO).
You can download it at
https://macdown.uranusjr.com/
It has two columns, one with your MathJax
and one with the formatted equations and text.
I use it all the time
for my submissions here.
I format them in MacDown
and then copy and paste
the MathJax into the answer or question area.
I save the .md files
so I can refer to or modify them later.
A: StackEdit (stackedit.io) is a nice Markdown + KaTeX editor in the browser for writing documents exactly as you would a Stack answer. I think documents are saved in local storage, so might not be ideal for use across multiple devices (haven't tested it), but it's convenient to draw up a quick document with math and save as a PDF.
It's very similar to MacDown and Obsidian recommended in the other answer, but run in-browser rather than locally.
