(11/27 - 6:25pm) I've just posted the solutions for HW12. I strongly recommend that you first try to solve the problems, and only then check the solutions! (I cannot stress this enough!) Otherwise you will not know if you are capable of solving problems on the final or realize what are your difficulties (on which you should work before the final).
(11/27 - 5:15pm) There will be no HW due on Tuesday (12/02) and no quiz in class.
(11/27 - 5:15pm) Here is some info about our final:
(08/18 - 12:00pm) Please, check this section often. I will put announcements and important info here.
(08/18 - 12:00pm) Please, hit the ``Refresh'' or ``Reload'' button on your web browser every time you visit this page, so that you can see the most recent updates.

Here is the Midterm I and the Midterm I with solutions.
The exams were graded and will be returned in class on Thursday (10/02). (You can check your grades in Blackboard.) If you are not in class that day, you have to come by my office to pick up yours. (I will not take them to class anymore.) The average was 69.24, the median was 61 and the highest grade was 97. So, the results were OK, but I thought they'd be better as the exam was easy. (Just check the solutions.)
Here is how I would curve these grades and the number of people with each grade:
Grade | Range | # of people |
A | 90-100 | 3 |
A- | 86-89 | 2 |
B+ | 82-85 | 3 |
B | 77-81 | 0 |
B- | 74-76 | 1 |
C+ | 70-73 | 2 |
C | 66-69 | 2 |
C- | 60-65 | 5 |
D+ | 57-59 | 2 |
D | 53-56 | 0 |
D- | 50-52 | 3 |
F | < 50 | 2 |
Note: This curve is just to give you an idea of how I curve. In the end I will not even look at this curve, I will just curve all the final averages.

Here is the Midterm II and the Midterm II with solutions.
The exams were graded and will be returned in class on Thursday (11/06). (You can check your grades in Blackboard.) If you are not in class that day, you have to come by my office to pick up yours. (I will not take them to class anymore.)
The exam might have been too long, so I considered the grade out of 80 instead of out 100 to compensate. On the other hand, most of what was in the exam you had seen before and so it should not have taken you as long. In any case, the average was 65.51 (out of 100, or 54.9 out of 80), the median was 64.38 (out of 100, or 52 out of 80) and the highest grade was 125 (out of 100, or 100 out of 80, i.e., a perfect score). The next highest grade was 98.75 (out of 100, or 79 out of 80).
Here is how I would curve these grades and the number of people with each grade:
Grade | Range | # of people |
A | 90-125 | 5 |
A- | 87-89 | 0 |
B+ | 83-86 | 0 |
B | 77-82 | 1 |
B- | 70-76 | 3 |
C+ | 65-69 | 2 |
C | 60-64 | 3 |
C- | 57-59 | 0 |
D+ | 53-56 | 0 |
D | 50-52 | 0 |
D- | 47-49 | 4 |
F | < 47 | 3 |
As you can see, the grades were very spread out...
Note: This curve is just to give you an idea of how I curve. In the end I will not even look at this curve, I will just curve all the final averages.

Here is the final and the final with solutions.

Math 300 is a basically a course on mathematical proofs. A proof is a series of logical steps based on predetermined assumptions to show that some statement is, beyond all doubt, true. Thus, there are two main goals: to teach you how think in a logical and precise fashion, and to teach how to properly communicate your thoughts. Those are the ``ingredients'' of a proof.
So, the topics of the course themselves play a somewhat secondary role in this course, and there are many difference possible choices. On the other hand, since these will be your first steps on proofs, the topics should be basic enough so that your first proofs are as simple as possible. Therefore, you will be dealing at times with very basic mathematics, and will prove things you've ``known'' to be true for a long time. But it is crucial that you do not lose sight of our real goal: do you know how to prove those basic facts? In fact, the truth is that you don't really know if something is true until you see a proof of it! You might believe it to be true, based on someone else's word or empirical evidence, but only the proof brings certainty.
In any event, the topics to be covered in this course are: logic, set theory, relations and functions, induction, and properties of the real numbers.
This course is clearly crucial to mathematicians, as our job is to prove things (and find things to be proved). But, this is a course also required for computer scientists, not only here at UT, but virtually everywhere. The most obvious reason is that computer programs are written using formal logic. Another relevant connection is Artificial Intelligence, where you basically have to ``teach'' a machine to come up with its own proofs.
Moreover, the skills taught in this course are universally important, and their benefits cannot be overstated! Everyone should be able to think clearly and logically to make proper choices in life, and you should be able to communicate your thoughts clearly and concisely if you want to convince, teach, or explain your choices to someone else. In particular, Law Schools are often interested in Math Majors, as the ability to think logically and clearly develop an argument is (or should be) the essence of a lawyer's job.
We will try to cover as much as possible of the text, but I'd like to cover at least the first 5 chapters. On the other hand, I might, and likely will, deviate from the book. I might just change the order of things a bit, but I might even change some topics, in which case your class notes would be quite important.
Homeworks will be assigned after every class and will be posted at the section Homework of this page. No paper copy of the HW assignments will be distributed in class. It is your responsibility to check this page often! Besides HW assignments, other important information will be posted here. (Check the section Important Notes often!)
The HWs will be collected on Thursdays. Each HW will have problems from the previous week (Tuesday and Thursday lectures). The problems to be turned in, as well as due dates, will be clearly posted here. The homework turned in will NOT be graded. I will look through them and keep comments for myself which will affect your final course grade from minus 5 points to plus 5 points (out of 100 points). People that do not turn HWs will have five points deducted from their final grades!
Since the HW will not be graded, we will have HW Quizzes every Thursday, at the beginning of the class. You will not have extra time if you are late. The quizzes will consist entirely of HW questions. You will have only ten or fifteen minutes, and so if you hadn't already solved it, you might not have enough time to come up with a solutions. Note that you will also be graded on how well it is written, not only if it is correct! (Remember, how to communicate your proofs is part of the course.) The same applies to exams and all graded work!
We will also have board work some Thursdays. I will ask for volunteers to do HW problems at the board for extra-credit. But, you will have to explain your solution to the class, not just write it down, and I will ask questions about it. It will count up to half of the points of a single quiz.
I will do my best to post solutions to the most difficult problems. If I do, they will be posted in this page.
In my opinion, doing the HW is one of the most important parts of the learning process, so the weight for them is greater than the weight of a single midterm, and I will assume that you will work very hard on them.
Also, you should try to come to my office hours if you are having difficulties with the course. I will do my best to help you. Please try to come during my scheduled office hours, but feel free to make an appointment if that would be impossible.
Finally, it is your responsibility to keep all your graded Quizzes and Midterms! It is very important to have them in case there is any problem with your grade. You can check all your scores at Blackboard. (Blackboard will be used only for scores. This is the official site for the course.)
There will be no make-up quizzes or exams. If you miss a quiz or exam and have a properly documented reason, your final will be used to make-up your score.
You will have to check your e-mail at least once a week, preferably daily. I will use your e-mail (given to me by the registrar's office) to make announcements. If that is not your preferred address, write me an e-mail letting me know ASAP. I will assume that any message that I sent via e-mail will be read in a week or less, and it will be considered an official communication.
I have an On-line Feedback Form where you can anonymously send me your comments and suggestions. I will consider your comments and try to do whatever I can to resolve possible problems before it is too late. So, please, feel free to use it whenever you have any constructive comment or suggestion. (In fact, I would greatly appreciate it.) If you don't want you comments to be anonymous, just send me an e-mail or come by my office and we can discuss the problem.

Academic Integrity
Study, preparation and presentation should involve at all times the student's own work, unless it has been clearly specified that work is to be a team effort. Academic honesty requires that the student present his or her own work in all academic projects, including tests, papers, homework, and class presentation. When incorporating the work of other scholars and writers into a project, the student must accurately cite the source of that work.
All students should follow the Honor Statement: from Hilltopics 2008/2009, pg. 11:
Honor Statement
``An essential feature of The University of Tennessee is a commitment to maintaining an atmosphere of intellectual integrity and academic honesty. As a student of the University, I pledge that I will neither knowingly give nor receive any inappropriate assistance in academic work, thus affirming my own personal commitment to honor and integrity.''
You should also be familiar with the Classroom Behavior Expectations.
Students with disabilities that need special accommodations should contact the Office of Disability Services and bring me the appropriate letter/forms.
