For this week, the professor Larry Zhang went over the concepts of conjunction, disjunction, negation, and truth tables. Actually the parts of conjunction and disjunction were not that hard since it is easy to transfer from English language to symbols. I only need to be careful when the difference of uses of conjunction 'and', between the meanings of 'the actual and 'union'. Except these, nothing was difficult.
Contrast to conjunction and disjunction, negation was hard for me. For example, I have no idea how and why the symbol of 'and' changes to the symbol of 'implies to'. I was trying to understand it by looking and finding in course notes, and websites, but I still do not get the concept at all. I believed I probably get some help on this concepts in tutorials, which I had today, but sadly it makes me more confused.
In order to understand the negation part, I believe I need to go office hour on next week, which might be solve my problems. Moreover I think only understanding lecture slides is not enough, so that I need to find the problems relating to lecture from the website that I can work on.
