Week 3

Blog post #3!

~~~~~~WEEK 3~~~~~~

Today's outline:

• Conjunctions
• Disjunctions
• Negations
• Truth Tables
• Manipulation laws

We started this class learning about conjunctions and disjunctions. I understood what both meant and the Ferrari example helped me fully understand the concept behind each one. I also learned the symbolic representation for conjunctions and disjunctions.

I found this joke during class very amusing. It was a good way to lighten up the mood.

A logician’s wife is having a baby. The

doctor immediately hands the newborn to

the dad.

His wife asks impatiently: “So, is it a boy or

a girl?”

The logician replies: “Yes.”

We then went onto learning about negation. I have learned it in MAT137 so I did not have trouble understanding. I found the negation exercise very easy and a confidence booster for myself. I usually am silent during class and do not participate as much but this exercise changed that. I started participating in class and I ended up learning from it as well.

However, I did not fully understand what scope meant and was left confused after class. Furthermore, I did not understand the implying part (Q->R) on the truth tables.

Next, we learned about De Morgan’s law. I understood it completely and have no difficulty in it. We also learned about Commutative laws, Associative law, Distributive law, Identity law, and Idempotent law. I did not understand them during class because I thought the professor Zhang was going over them too quickly, but I revised them at home and I understood them.

I did not understand this week’s tutorial properly. I think there should be example of a question which should be done; it would help me understand how to attempt the question and how to construct the answer. I did not fully understand this week’s tutorial and I know I did not do the quiz well. I will study more for the upcoming tutorial and I will do well hopefully.
