Basics: Combining Words and Equations
Following the rules of grammar.
Good writing observes the rules of grammar. This applies to writing in mathematics
papers as well! When you write in a math class, you are expected to use correct grammar
and spelling. Your writing should be clear and professional. Do not use any irregular
abbreviations or shorthand forms which do not conform to standard writing conventions.
Mathematics is written with sentences in paragraphs. (And yes, paragraphs are important.
It is not amusing to read a three-page paper consisting of just one paragraph.)
