**About the reading reports:**

· **Effort (2
points):** How much time have you spent for the reading?
What percentage of the contents in the reading do you think you understand?
Have you come to the class this week? **Assessment**: The student is
expected to **(i)** have attended the
class this week at least once (0.5 point), and**(ii) have either **gained
a good understanding of **80% or more of the contents** **or** have
spent at least **three hours** in the reading (1.5 points).

· **Reflection on
the reading (2 points)**: Put down 1~2 paragraphs of your thoughts such as notes of new
insight you gained, interesting things encountered, questions of things you
don’t understand, and so forth.** ****Assessment**: the student is
expected to show substantial evidence of understanding or effort of trying to
understand the contents in the reading.

**Week 1: Introduction
to Propositional Logic**

**Reading #1**due Wednesday,**Jan. 23****:**(i) Read Sections 1.1 and 1.3 in Discrete*Mathematics and Its Applications*, 7th Ed. Submit your report online under Canvas. (ii) Read Section 1.2 if it takes**less than****3 hours**for you to read 1.1 and 1.3 in (i).**Homework #1**Wednesday,**Jan. 23****: Please click here**to download**propositional logic.**Either**hand in your work on paper**in the class or**scan and upload an electronic version**under Canvas.**Notes on Homework #1****:**(i) For problem #1 and #3, your compound proposition should only be composed of the three atomic propositions D4, D100 and D400, parentheses as needed, and the logic operators ˄, ˅, and ̚ as needed. Don’t use other logic operators. (ii) For problem #5, please do include 8 rows in the truth table, corresponding to all the 8 possible combinations of truth values for three independent atomic propositions. Do so even though the truth values D4, D100 and D400 are dependent and some of the 8 combinations could not happen.
