  • Everyone makes honest mathematical mistakes, but there is no reason to get in your own way by writing your proofs with incomplete sentences and other grammatical mistakes, by using undefined symbols for variables or by engaging in other forms of sloppy writing. Mathematics must be written carefully, and with proper grammar, no differently from any other writing.
  • This course will offer many opportunities to practice the careful writing of mathematical proofs. Properly written proofs require the writer to observe the following basic points.
    • Write your homework assignments neatly and clearly.
    • Justify each step in a proof, citing the appropriate results from the text as needed.
    • Use definitions precisely as stated.
    • Use correct grammar, including full sentences and proper punctuation.
    • Be very careful with quantifiers.
    • Strategize the outline of a proof before working out the details; the outline of a proof is always determined by what is being proved, not by what is known.
    • Distinguish between scratch work and the actual proof; scratch work can be in any order, but the actual proof always starts with what is known and deduces the desired result.
    • Proofs should stand on their own; check your proofs by reading them as if they were written by someone else.

  • Proofs-based mathematics courses are very different from computation-based mathematics courses such as Calculus. The ways you studied, did homework and took exams in computation-based courses was appropriate for those courses, but not for proofs-based courses. Approach proofs-based courses with the idea that you will be doing things differently from what you did in computation-based mathematics courses.
  • The material in this course is much more abstract, and requires much more precision in both studying and problem solving, than the material you saw in courses such as Calculus. Some students find the material in proofs-based courses more difficult than the material in Calculus courses, and, for some students, a proofs-based course such as this one constitutes the first time that they found a mathematics courses challenging, which can be intimidating at first, but is in fact completely normal. Everyone, including the very best mathematicians, reaches a level of mathematics that he or she finds difficult; what varies from person to person is only what that level is. If you made it this far in mathematics and you only now first encounter substantial difficulty in learning the material, you are doing fine.
  • In general, the more advanced you get in mathematics (or any subject), the larger the percentage of learning that takes place outside of class, including from the textbook, from other sources, from office hours, from tutors and from your fellow students (not necessarily in that order).
  • In Calculus courses, where the material can mostly be learned in class, reading the textbook is not necessarily very important. By contrast, in proofs-based courses reading the textbook carefully, and seeking help with those parts of the textbooks that you find difficult, is crucial.
  • In Calculus courses, solutions to homework exercises are usually written as a collections of equations, with little or no words explaining the solution. By contrast, rigorous proofs are, fundamentally, convincing arguments, and to make a good argument, words are needed to direct the logical flow of the ideas; to explain what is assumed and what is to be proved; and to state what previous results are used. In particular, rigorous proofs are written using full sentences, and with correct grammar and punctuation, because doing so helps make the arguments more clear and precise.
  • In Calculus courses, solutions to homework problems are usually written directly, with little revision. By contrast, rigorous proofs should be written the same way a paper in a humanities course is written, by first making an outline (often called 'strategizing a proof'); then sketching out a rough draft; then revising the draft repeatedly until the proof works; and, lastly, writing the final draft carefully, and, when required, typing it (via (mathrm LaTeX)).
  • Revising a draft of a rigorous proof should be done exactly as revising a draft of a paper in a humanities course, which is to read it as if you are not the author, but rather as if you are someone else in the class, and making sure that each sentence makes sense as written, without recourse to unwritten explanations.
  • Learning to write rigorous proofs takes time, and you should not expect to master it instantly.
  • A very good way to improve your skill at writing proofs, and also to do better on the homework in this course, is to bring a draft of each homework assignment to office hours before you write up and submit the final draft.
