This week we talked more about math languages. We also had a very interesting discussion about the relationships of the English language and the mathematical ways of interpreting a sentences in our tutorial.
The discussion in our tutorial was mostly on the cause and effect and how we interpret them. I remember the other peers were talking about an example of "all astronauts likes to eat oranges, then it must be that eating oranges is a cause for them being astronauts". There were confusions first, but at the end I think we came to an agreement that eating oranges is only one of the factor that they are astronauts, but not necessarily the determining factor.
As for me, I am having a little trouble with the negation part of the lecture. Mainly because if you bracket up a sentences full of symbols, and put a negation sign in the front, it will take me some time to switch up all the signs, so I am going to practice more of that and hopefully in assignment 1 as well.

Week 1 & 2
Week 1
This week we talked about some introduction things and why we need mathematical language to do well in CSC 165.
Last year I took Danny's CSC 104 in the fall and I had a very good impression on his teaching style! I hoped to get him this year but unfortunately my timetable did not work out. However, I think Larry's teaching style is just as good so far, his example is very clear and easy to understand. I was particularly impressed with his approach to lead us find the kids' age, we first analyzed the statements given and took out some unneeded parts and finally came to a result.
Since I have some backgrounds on math last year I feel pretty confident with the materials covered so far.
Week 2
This week we mostly focused on the 'for all' and 'there exists' symbols. The methods of using the venn diagram to understand them is kind of new to me, but after a while I think I can fill them out with 'X', 'O'.
We also worked on some sets symbols, and statements vs. sentences.
I am still a having a little problems with statements vs. sentences, but I am getting better at differentiating between them. My understanding so far is that you can always give a statement True/False, but for sentences you can't?
Implications and equivalences were good for me, I fell pretty confident about them.
