Ten simple rules for mathematical writing
Mathematical writing is the type of writing where mathematics is used as a primary means for expression, deduction, or problem solving. It is fundamentally different from creative and expository writing for two main reasons:
- it involves the interplay of two languages (natural and math),
- it requires much slower reading (it expresses complex ideas that must often be read and pondered several times).
As a result, many of the rules and suggestions found in writing style manuals are inadequate and/or do not apply. We propose an approach to mathematical writing, based on a set of simple composition rules. These rules are outlined in a slide presentation from an April 2002 lecture at MIT (edited later), and focus on the structure of the entire document (the content and the interconnections of different parts):
* Organize in segments
* Write segments linearly
* Consider a hierarchical development
* Use consistent notation and nomenclature
* State results consistently
* Don’t underexplain – don’t overexplain
* Tell them what you’ll tell them
* Use suggestive references
* Consider examples and counterexamples
* Use visualization when possible
