Is LaTeX the best for formulas?

Question

Markdown

I'm planning to write math and computer science notes using Markdown
Is LaTeX the best thing mankind has come up with for writing LaTeX formulas, or are there any good/better analogues?

Answer 1

Yes.
There are no alternatives for an electronic document.
How to make a Markdown + LaTeX document - there are different options.

Answer 2

Latex is not so much for formulas, but for professional layout of scientific materials. Your lecture notes are clearly not professional material. Better yet, by hand.
