Quick & dirty way, if it's just a few characters, is just to find them
on the web, copy and paste, save to file, keep the file open in a
window, and then copy and paste when you need them. From
https://en.wikipedia.org/wiki/List_of_logic_symbols:

Your text file is already using unicode. Nothing defaults to ASCII
anymore.

If it survives the initial cut and paste from the web to your Emacs
file, it should be fine. (Notice that the symbols in the TEX column
here: https://en.wikipedia.org/wiki/List_of_mathematical_symbols don't
survive!)
Now, there are ways to assign things to keys, or keystroke combinations;
and further, there are also systems like SWEAVE and Auctex to let you write
complicated equations, but this should get you started.
