Hi everyone,
Your Midsemester Grades are available in the OpenLab Gradebook. These grades are not a part of your official academic record – they are intended as check-in on how you are doing in the class.
The Midsemester grade will be one of the following: P=Pass, BL=Borderline, U=Unsatisfactory. It is based on your Midsemester %, which is calculated as follows:
- Homework 30% – this includes both WeBWorK and written assignments.
- OpenLab 25% – this includes all writing assignments on the OpenLab
- Exams 45% – this includes exams #1 and #2
Let me know if you have any questions or concerns,
Prof. Reitz
Hi everyone,
The grades for Exam #2 are posted under OpenLab Gradebook (link to your graded paper appears in the grade comments, as usual).
I’ll see you in class tomorrow – Let me know if you have any questions.
Best,
Prof. Reitz

In your homework, you are asked to prove propositions that involve the gcd. It may help to keep the following in mind:
To prove that a number
We need to show two things:
1.
2. if
Here is an example, so we can see how it works in practice:
Proposition. If
