Week 1-2 sLOG

School has started for almost two weeks already, and topics that taught in class have started to get more into the main theme of the course. For the first week, the topics are mostly introductions into computing logics, such as what sets are, if a statement is correct or incorrect in a given circumstance, and Venn diagram. For the second week, more symbols and signs are introduced to represent certain logics, which is fairly simple for me, as I have taken MAT137, which is more like a proof course, and sings and symbols use in it are rather similar.

The main problem I had was with the Venn diagram, which I was not very familiar with. When the professor first introduce it on class, I thought it won’t be useful, since it can be easily represent by writing all the statements and facts out.  However, when I was working on the tutorial exercise #1 which was asking us to create certain Venn diagram to represent different statements, I found that it is not that simple. I do know that the square box represents everything in that case, the two circles represents two different sets, and the intersection between them are the common value(s) that they have, but I was not sure what are the sets, as for different cases, we have to assign to different sets. After going to the tutorial, I have a much better understanding for Venn diagram, and be able to produce them in the short quiz. Now when I do my other programming course (CSC148), I found Venn diagram to be extremely useful, as in it can clear many things up, such as which data are in common with others, which are not; it really helps with the thinking before actually doing the coding part.
