Combinatorics is called the art of counting without counting.

Ugh, combinatorics. It's the topic I like the least. When we discussed this topic in our Stat1 class last semester, I didn't even bother to listen. Gaaaah. This coming semester, if I finally got the chance to take Cmsc57, I'd say hello to *drumroll* combinatorics again.

BUT... But I was able to get hold of the book Discrete Mathematical Structures in Computer Science. Yay! Thanks to my orgmate who lend it to me. I hope it'll be less difficult for me now.

I wonder where they got this book. -.-
