The sheer volume of advice available “out there” on writing mathematics can be quite intimidating. Here’s a (nonexhaustive) list of interesting pieces. Many of these were found by undergraduate researcher Artur Araujo.
Writing mathematics well (audience is mathematicians)

 How to Write Mathematics, by Steenrod, Halmos, Schiffer, and Dieudonne
This book is a collection of four essays by Norman E. Steenrod, Paul R. Halmos, Menahem M. Schiffer, and Jean A. Dieudonne. It was originally published in 1973 by the American Mathematical Society.
Paul Halmos’ paper on “How to Write Mathematics” is here and is summarized in Ivars Peterson’s blog post Paul Halmos on Writing Mathematics.  L. Gillman, Writing Mathematics Well: A Manual for Authors, The Mathematical Association of America, 1987.
A short manual, with many good tips. The appendix is available here: “The Use of Symbols: A Case Study.”  J.S. Milne has a webpage of sarcastic Tips for Writers.
 A Primer of Mathematical Writing: Being a Disquisition on Having Your Ideas Recorded, Typeset, Published, Read & Appreciated, by Steven G. Krantz
Published in 1996 by the American Mathematical Society  Handbook of Writing for the Mathematical Sciences by Nicholas J. Higham,
Published in 1998 by SIAM  I Want to Be a Mathematician: A Conversation with Paul Halmos, by George Csicsery
Halmos discusses writing, teaching, and research (44min film ) Trailer  “Some Hints on Mathematical Style,” by David Goss
This 4page collection of “hints” is based on advice the author received from J.P. Serre as well as on experience publishing a conference proceedings and editing the Journal of Number Theory.  “Advice for amateur mathematicians on writing and publishing papers” by Henry Cohn
Contains helpful advice that professional mathematicians typically learn from their advisors.  “Three Sins of Authors in Computer Science and Math” by Jonathan Shewchuk
This online essay is written in an irreverent style that may help to make the advice memorable. Advice includes “Get to the point!”
 Rather than listing a paper’s contents in a paragraph at the end of the introduction, “I submit that the references to each section of the paper should have been folded into the introduction, each appearing in its logical place.”
 “Conclusions should synthesize the results of your paper and separate what is significant from what is not.”
 R. P. Boas, “Can We Make Mathematics Intelligible?” American Mathematical Monthly 88, 1981, pp. 727731.
This 5page article by an editor of the American Mathematical Monthly uses humor to (somewhat scathingly) point out common pitfalls with mathematical writing. Addresses aspects of terminology, symbolism, proofs, rigor, enthusiasm, skills, and lectures.  Mathematics Into Type, by Ellen Swanson and Arlene O’Sean, AMS, updated 1999.
This book is directed less to authors than to editors who have little or no mathematical background.

Leonard Gillman writes of the classic 1965 edition, “The peerless classic, revered for the wit and artistry of its writing as much as for its pungent advice. Must be sampled slowly; ideal for browsing: pick out any page and enjoy the language…” (Quoted from the bibliography of Writing Mathematics Well: A Manual for Authors, by Leonard Gillman, The MAA, 1987.)  “How to handle authorship disputes: a guide for new researchers” by Tim Albert and Elizabeth Wager
The mathematics convention of listing authors alphabetically by last name avoids some of the issues addressed in this article, which is written for the biomedical fields. Although conventions vary by discipline, this thoughtful article may be a good starting point for considering the range of authorship questions; e.g., When should a colleague be a coauthor vs. mentioned in the acknowledgements section?

 Undergraduate Guide to Writing Mathematics (unpublished) by Stephen B. Maurer
With patience and good sense, Stephen Maurer explains for undergraduates myriad aspects of how to write as a mathematician. This book addresses taking notes, writing reports, giving presentations, and revising. Particularly valuable is the second half of the book, which provides advice on diverse topics such as proofs, definitions, word choice, style, when and how to punctuate displays, and when and how to use citations, examples, figures, footnotes, humor, etc. The book also includes a glossary of mathematical terms and an extensive collection of writing exercises.

 This brief handout by Olivier Bernardi addresses not only the characteristics of a good math term paper but also the process of writing one.
 Undergraduate Guide to Writing Mathematics (unpublished) by Stephen B. Maurer

 “Maximum Overhang” by Paterson et al. received an MAA writing award in 2011. This pdf of the article is annotated to point out to students how to write a mathematics paper. The annotations address the structure and content of an introduction, how to integrate equations, text, and figures, how to guide the audience through the content, how to cite, etc. The article addresses the question of how far a stack of blocks can extend from the edge of a table. It was published in the American Mathematical Monthly 116, December 2009.

 Steven Kleiman’s “Writing a Math Phase Two Paper”
Guidance for how to write a math paper, written for a now defunct writing requirement but with much good general guidance. Topics including organization, use of language, and presentation of mathematics (e.g., symbols and formal arguments). A short example of mathematical writing is included. Because the guidance is written in the form of a journal article, the .tex file can act as a template for students to use to create their own papers.  Haynes Miller’s notes on writing mathematics
These 8page notes address the parts of a paper; mathematical style for attribution, citation, and internal references; the distinction between belief and proof; and a miscellany of 15 common errors. These errors range from grammatical issues such as articles and comma splices to errors of precision, notational consistency, and sequencing of information. Examples are included.  Writing a Research Paper in Mathematics, by Ashley Reiter
This webpage summarizes ideas presented in the book How to Write Mathematics, by Steenrod, Halmos, Schiffer, and Dieudonne, and includes thoughts from the author’s experience as well. The site addresses introductions, structuring a paper, formal and informal exposition, writing a proof, and includes a list of 14 specific recommendations ranging from the small scale (“…never use “any” in mathematical writing. Replace it by ‘each’ or ‘every’…”) to the large (“There should be a clear definition of the problem at hand all the way through.”)  Krantz, Steven G., “How to write your first paper.” Notices Amer. Math. Soc. 54 (2007), no. 11, 1507–1511.
 Language of Mathematics (unpublished), by Warren W. Esty
This textbook is written to an audience of nonmath majors and elementary ed students. From Chapter 1, “The goal is for you to become fluent in the symbolic language of mathematics so you can efficiently read, write, learn, and think mathematical thoughts.” (Math Forum abstract)  See also this website’s page for English learners and global English as well as the pages on General Principles of communicating mathematics.

 “A TwoGenie Strategy Helps Students Write Weekly Papers,” by R. G. Montgomery, PRIMUS, Vol 4, No 4, 1994, pp. 347358.
Abstract: “Mathematical Perspectives” is a seminar required of beginning math majors at Southern Oregon State…The talks are complemented by reading assignments, and therein lies an instructional challenge: insuring attentive reading by participants in a Pass/NoPass onecredit seminar which has no examinations. Short written papers do the trick…But, the challenge is now is to elicit papers which are wellfocused, easy to evaluate, and amiable to an instructor’s comments. This article tells how two playful genies, Alf and Bet, bottle this writing challenge.
