Yay! I’m not the last one to post this week!
Inspired by Cecilia’s Week 7 Reflection, I will not start this week’s reflection with another “This week…”.
Six days ago, I relearned sets and Venn Diagrams. I have to admit, they are pretty fun, at least, more fun than formal proofs (emphasis on the formal; I am not going to complain about informal proofs, like proof by fire…hahaha..). I also relearned the Inclusion-Exclusion Principle. It is basically just common sense, so it was really easy to comprehend.
I learned a lot of somewhat new symbols, as well as new vocabulary, which are just fancy representations of what I already know and a good tool for confusing my friends. I also learned about set builder notation, which was much easier than I had thought now that I actually understand it.
I still don’t understand, though, the relationship between the universal set and the empty set. The empty set is a subset of every set, so it is a subset of the universal set, right? But then, isn’t the complement of the universal set the empty set? It is so confusing! Or is it just me?
See you guys tomorrow! Bye!
Oh, and Sam, if you want to meet someone really sneaky (**shudder**), meet my history teacher, Mr. Graf. I’ll never look at white posters the same way again. Hahaha! Get it, Irene? By the way, if you haven’t figured it out yet, it is an inside joke.
