Hello, guys. Here’s a correction for Homework 2 Solution :

• In Problem 3, the maxterm(极大项) $M_5$ should be $\neg p\vee q\vee \neg r$，not $\neg p\vee \neg q\vee r$. There’s a mistake in the old version.

Sorry for the inconvenience, and thanks to the student who pointed out this mistake.

• We have set up a questionaire for the course. And I wish you can actively provide the feedback about this course. See more information in Discrete Mathematics.

Happy Mid-Autumn Festival and National Day!

Considering the course schedule, Homework #2 only needs to finish the problem 1, 2, 3, and 5 this week.

• Please note that we have modified the problem 2 to just require finding the Conjunctive Normal Form (合取范式，CNF)and Disjunctive Normal Form(析取范式，DNF), insteading of finding Canonical Conjunctive Normal Form (主合取范式)and Canonical Disjunctive Normal Form (主析取范式). The PDF will be updated soon later.

Homework #2 is now available. See more information in Schedule.

Here’s the explanation for the why $\rightarrow$ doesn’t share the associative law:

let $A=0,\ B=1, \ C=0$, then we have:

• $(A\rightarrow B)\rightarrow C =0$
• $A\rightarrow (B\rightarrow C)=1$

Homework #1 is updated by fixing a typo. Thank you for the student that point out the mistake.

Homework #1 is now available. See more information in Schedule.
