This question already has an answer here:
I'm enrolled in a mathematics course where we are supposed to return our solutions to weekly exercises as PDF files. There seems not to be any general official guidelines other than "it's legible", e.g. one can take a photo / scan handwritten text, but I want to practise my latex skills.
Could you recommend useful packages, templates and any other resources for producing good-looking and readable exercise answers?
I'm a relatively inexperienced in LaTeX.
