Week X

Firstly, the problem set was due on this week. The question seemed to be very insteresting because it sounded very obvious and because it was so obvious, I was quite confused on how to prove. This is one of common situations that everybody would agree with this that when there is something that it is so true, definite, and obvious, it might confuse you because it sounds very easy!. So, before trying to prove, I looked up the lecture notes first and refreshed my brain with all of the definitions. After, I wrote something and brought it to the TA centre to check if he agrees or not. I realized it was simple, not even induction needed.

due to busy days, I could not attend the lecture. I might look up some slide later to catch up.
