Hi everyone,
The review sheet for the final exam has been posted under Classroom Resources / Exam Reviews
. As always, let me know in person, by email, or here on the OpenLab if you have any questions.
NOTE: The Review Sheet contains solutions to most, but not all, problems – the rest of the solutions will be added this weekend.

Hi everyone,
The review sheet for Exam #3, taking place on Tuesday 11/27, is posted under Classroom Resources / Exam Reviews
. As always, if you have any questions or notice any errors please let me know (by email, in person, or here on the OpenLab).

UPDATE: The exam will cover through Sec 2.9 only. Problem #16 on the review sheet will NOT be on the exam (although it may appear on the second exam).
The first exam will take place on Tuesday, October 2nd. The review sheet is posted under “Classroom Resources/Exam Reviews” – it is the same as last year’s Exam #1 Review. Please let me know if you have any questions, or to report an error.

Hi everyone,
I’m writing to follow up on a discussion we had in class today, regarding methods for translating conditional (“if…then”) statements from English to symbols.
We started with:
If it rained, the ground got wet.
Which we symbolized as
R -> W
Where R = “it rained” and W = “the ground got wet”.
We then got stuck on the phrase:
It rained only if the ground got wet.
The correct symbolic version of this is:
R -> W
just as it appeared in the slides, where R = “it rained” and W = “the ground got wet”, just as before. This is counterintuitive, but true!
For a longer discussion, with some better examples, take a look at this page (otherwise, just memorize it!):

WeBWorK is accessible from on and off campus (anywhere you have access to the internet). Your first WeBWorK assignment is due on Tuesday, September 4th, at midnight, and will cover the material from the second day of class. Here’s what you have to do:
Assignment. To get started , you must complete the following three steps.
Step 1. Log in to WeBWorK here: http://mathww.citytech.cuny.edu/webwork2/MAT2071-F18-Reitz. I have created Usernames and Passwords for each student registered for my class.
Username. Your username for WeBWorK consists of your first initial plus your last name, all lowercase (for example, John Smith would have username ‘jsmith’).
Password. Your temporary password is the same as your username (if your username is ‘jsmith’, your password is currently ‘jsmith’).
Step 2. Change your password and update your email address. To do this, select “Password/Email” from the main menu on the left. Use whatever email address you like (I suggest using one that you check often).
Step 3. Complete the first assignment, titled Assignment1-Sec1.2-1.3. Click on an assignment on the main screen to get started.
If you have any trouble – either with logging in, or with completing the assignment, post a comment here or send me an email and I will get back to you.
WeBWorK Tips:
This course is MAT 2071, Introduction to Proofs and Logic, taking place in the Fall 2018 semester with Professor Reitz. We will be using this website in a variety of ways this semester – as a central location for information about the course (assignments, review sheets, policies, and so on), a place to write about the work we are doing, to ask and answer questions, to post examples of our work, and to talk about logic, proofs, mathematics, reality and so on.
