(12/09 - 11:05am) Your average will be computed in the following way. I will drop your lowest HW/Quiz score when computing your Quiz/HW average. Then, if you did not miss more than a two HWs/Quizzes, then your course average will be the greatest value between 0.25*HW + 0.20*(Mid1 + Mid2) + 0.35*Final (the way made explicit in the syllabus) and (0.20*(Mid1 + Mid2) + 0.35*Final)/0.75 (so, the HW are not considered). The bottom line is that the HW can only help you. On the other hand if you missed more than two Quizzes/HWs, your course average will be computed as in the syllabus (i.e., 0.25*HW + 0.20*(Mid1 + Mid2) + 0.35*Final).
If you did not turn in your HW/Quiz for health reasons (and I told you that I would replace your score with your final), then this score will count (as usual), i.e., you will not be penalized.
(12/01 - 9:00am) I have just written the final exam. Here is some info about it:
(09/09 - 7:40am) Change in make up work policy: As recommended by the university administration, I will not require a doctor's note in order to make up for missed work anymore. The change was suggested to avoid encouraging sick students to come to class while still contagious, and to prevent the Student Health Center to receive more appointments that necessary.
(08/16 - 7:00pm) Please, check this section often. I will put announcements and important info here.

Here is the Midterm I and the Midterm I with solutions.
The exams were graded and will be returned in class on Friday (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 61.18, the median was 56 and the highest grade was 91. So, the results were not good.
Here is how I would curve these grades and the number of people with each grade:
Grade | Range | # of people |
A | 89-100 | 2 |
A- | 80-88 | 1 |
B+ | 77-79 | 1 |
B | 75-76 | 1 |
B- | 65-74 | 2 |
C+ | 55-64 | 1 |
C | 50-54 | 1 |
C- | 47-49 | 2 |
D+ | 45-46 | 0 |
D | 43-44 | 0 |
D- | 40-42 | 0 |
F | < 40 | 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 Friday (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 results were mostly OK. This was the sort of exam that shows who are working on the class, as all the problems were very similar to HW. So, the grades were distributed among very good and very bad grades, with just a few in between. In any case, the average was 75.87, the median was 78, and the highest grade was 100. You can see the statistics at Blackboard.
Here is how I would curve these grades and the number of people with each grade:
Grade | Range | # of people |
A | 90-100 | 6 |
A- | 87-89 | 0 |
B+ | 83-86 | 0 |
B | 80-82 | 0 |
B- | 77-79 | 1 |
C+ | 70-76 | 1 |
C | 65-69 | 1 |
C- | 63-64 | 0 |
D+ | 60-62 | 2 |
D | 55-59 | 2 |
D- | 50-54 | 0 |
F | < 50 | 2 |
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: final and 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 due on Wednesday, when you will either turn in your HW or take a quiz on problems taken directly from the HW set due on that day. In the former case, two or three problems will be graded and count the same as a quiz. In the the latter, the HW will not be collected at all. You will not known in advance if the HW will be collected or if there will be a quiz, and hence you should be prepared for either one.
The quizzes will take place at the beginning of the class. You will not have extra time if you are late. You will have only ten or fifteen minutes to take a quiz, and so if you hadn't already solved the HW problems, 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!
Points will be taken from messy solutions in all assignments, and you need to show work in all questions (unless stated otherwise)! (This same applies to quizzes, HWs, exams and all graded work!)
Calculators will not be allowed! (This includes HW, quizzes, and exams!) As you will see, you won't miss them either.
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, HW, 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 or due to sickness, 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, please make sure to forward your university e-mail to it!) 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
The university expects that all academic work will provide an honest reflection of the knowledge and abilities of both students and faculty. Cheating, plagiarism, fabrication of data, providing unauthorized help, and other acts of academic dishonesty are abhorrent to the purposes for which the university exists. In support of its commitment to academic integrity, the university has adopted an Honor Statement.
All students should follow the Honor Statement: from Hilltopics 2009/2010, 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.

Please read: I will try to post here a few solutions. The new solutions will be added to this same file. They might come with no explanation, just the ``answer''. If yours do not match mine, you can try to figure out again. (Also, read the disclaimer below!) You can come to office hours if you want explanations for the answers. Be careful that just because our ``answers'' were the same, it doesn't mean that you solved the problem correctly (it might have been a ``fortunate'' coincidence), and in the exams what matters is the solution itself. I will do my best to post somewhat detailed solutions to the harder problems, though.
Disclaimer: I will have to put these solutions together rather quickly, so they are subject to typos and conceptual mistakes. (I expect you to be a lot more careful when doing your HW than I when preparing these.) You can contact me if you think that there is something wrong and I will fix the file if you are correct.
