CSC 165 SLOG #3: Another Challenge (Week 4)

As I start a new week, I began to find CSC 165 more challenging than before. Double quantifiers were the hardest material for me to understand. Despite I read over the notes again, I still found the material I learnt this week as challenging. What I found easy was the tutorial and the quiz I had this Tuesday. De Morgan's Law and transforming -> to (not) and (or) for equivalence was the easiest thing I did this week. I was able to understand very quickly. I hope to get 2/2 on this week's quiz.
To demonstrate my understanding on De Morgan's Law, distributive law and etc, I decided to solve one equation that I made it myself.

P(x) → Q(x)∧R(x) <->¬P(x)∨(Q(x) ∧R(x)) 
                            <->(¬P(x)∨Q(x)) ∧(¬P(x)∨R(x))

What I found interesting was that as I practiced for the tutorial, I get used to tranforming and using De Morgan's Law.

However, the proof was another obstacle that I had to overcome. The concept of approaching to infinity was easy since I already learnt that in Math. However, other proof to prove various mathematical expression was so confusing to me.

Learning transitivity was easy as I was able to understand in one glance. The professor has given us an example for transitivity which is shown below.

∀x∈ X, (P(x) → Q(x)) ∧(Q(x) → R(x))

Not altering the truthfulness was very challenging for me and I had so much problem to understand that. As we explore more on logic and mathematical expression, it gets more challenging. 

Last thing I want to talk about is CSC165 Assignment #1. I worked with one other person to complete the assignment. Question 4 on assignment was very challenging to me, because at first, I thought that there should 3 sets existing. However, I realized that one set is universal set and two sets are within the universal set. Negation and changing symbolic form to English and vice versa was very easy to me as I have already practiced a lot during the last weekend. I hope that I do well on this assignment, because I believe the first assignment should be the easiest one among three assignments. 

Now that I have my first CSC165 mid-term test coming up, I plan to study 5 to 6 hours over the weekend. Although I have already been studying for the test, the practice makes perfect. So I will keep putting my effort into study. Let's do this! I hope to achieve high marks!
