Homeworks that are typeset will receive up to 4% extra credit. Full extra credit is easier if typesetting is done in LaTeX. Many students have had success with Overleaf, but you can also use pdflatex on Linux and MiKTeX on Windows. LaTeX sources are available for each assignment, and make good templates for your submissions.
Requirements for typesetting credit:
You must use the correct symbols. The symbol for implication is →, not ->.
It is better to write the symbols by hand than to use ASCII-art.
Reminder: this does not apply to reading assessments.
If you need to find a symbol, I recommend the detexify webpage.
Elements of typesetting that I look for.
Problems are clearly numbered and separated.
If problems are restated (always nice to see), then they are clearly separate from the solutions.
Within each solution, spacing and indentation reflect the logical flow of the document.
Arguments that should be paragraphs are in paragraph form, while arguments that should be itemize or enumerated are itemized or enumerated. You should almost never have one-sentence paragraphs.
