**Description:** This class covers foundations of discrete mathematics and
introduction to proofs. Topics include Propositional Logic, Sets,
Relations and Functions, Methods of Proof, Counting, Modular Arithmetic, RSA Cryptography and Graph Theory.

** Textbook: **
We are using __Mathematics: A Discrete Introduction__ (2nd edition OR 3rd edition) by
Edward Scheinerman. It is available at the bookstore and many other places, in multiple formats (new, used, rental, digital)

** Grading: **
Your grade is based on 3 exams plus a final, plus your hw as
follows. 85% of your grade is based on e1+e2+e3+f+f, except you get to drop
the lowest of the 5 scores (final is 2 scores). 15% is based on homework.

**Homework: **HW assignments are posted on Piazza and will be submitted via Gradescope. Instructions for submitting homework will be posted on Piazza. Homeworks are due Sundays at 11:59pm.

Late homework: You are allowed four "tokens" to be used at your discretion for a 24-hour automatic extension on the homework. Other than this, late homework will be counted as 0. You are responsible for keeping track of whether you have used the tokens or not; computations are simply based on the timestamp from Gradescope on your submission. Don't waste tokens on being 2 minutes late!

HW collaboration policy: You are welcome to talk to the Instructor, TAs or
other students about HW problems, but if so please follow the "sandwich" rule: first read and think about the problem by yourself, then work with others if desired, and then * the final form that you
turn in for grading should be written by you alone using your own
words.* You should not be looking up hw solutions on the Internet.
If you have substantially collaborated with other students
on a problem, please acknowledge this at the top of that problem,
i.e. "I worked with Alex and Robin". The write up still
needs to be your own. In general, you should assume that problems require justification---no credit for correct answers with no justification.

Typesetting homeworks using LaTeX (optional but recommended): In order to run LaTeX you will need to install a free LaTeX distribution. Alternatively, you can use the lab machines, remote login (ssh & sftp) (non EECS majors can get an account @ EECS systems office), or online LaTeX editors such as Overleaf.

- Installation: You can choose whichever distribution you prefer. Here are some popular ones:
- Editor: Although not required, you might want to also install an editor. Some popular ones are TeXStudio and TeXMaker (both cross-platform).
- Template/example:
- Template/example .tex file
- Sample image (from
Wikipedia:Graphs)

You**must**copy this file next to the example tex file to compile because it is used as an example of placing images in your documents. - PDF version

- Compiling: using an editor or runnig
*pdflatex [myfile.tex]*

**Exams:** TBD (3 exams)

**Final Exam:** We will use the standard Tufts final exam blocks:

E block (section 03), final exam is Wed May 8 from 3:30–5:30pm, in our usual classroom.

H block (section 04), final exam is Tue May 7 from 3:30–5:30pm, in our usual classroom.

**Missing homeworks/exams:**If you have a serious reason for not submitting homework or not taking an exam, you should notify your Dean and/or Health Services, and of course you may copy us as well. Decisions about missed homeworks/exams will be made in consultation with your Dean. Otherwise, exams must be taken at the scheduled times. Check the exam schedule before making travel arrangements.
