Class Overview

In this class, we will leave the computational aspects of mathematics, and step into the theoretical and logical side. As the first upper division math class for most of you, this course will prepare you in understanding logic, as well as reading and writing basic proofs, which will be requried for all your future math and a lot of other classes.

The class will not be in a traditional "lecture-only" style. I will ask you to actively participate. This includes have you work and talk both as a small group in class, and in front of everyone. See "Reading" in Syllabus.pdf.

Attendance is not part of your grade, but it is required via oral presentation. If I pick a person to present and they are not in class, they get a 0 for the presentation.

To encourage an engaging learning environment in the classroom, there will not be podcast or recordings available. If you have to miss a class, be sure to ask your classmates for what you have missed, and come to office hours to catch up if needed.

Office Hour

If you are not sure what "office hour" is, it is an opportunity for you to talk to me about the class, seek help in topics you are unsure about, discuss the homework problems you are stuck at. A lot of students tend to be intimidated to talk to the instructor, fearing that they are judged for not knowing the material. The fact is, we are trying to help you succeed, and we do not evaluate student at all during office hours. A student who comes to office hours regularly will generally leave a good impression to the instructor, in contrast to the misbelief that the instructor would think such student is not performing well. So, if you need anything, come to office hours. Seek help soon, rather than later!
