B.O.B.- Moment of clarity

Throughout this unit I think the hardest thing for me to understand was interval notation. I had missed a couple days of school so that didn't really help me at all. So while I was trying to juggle the things that I had missed I was also trying to get a grip on interval notation. Interval notation doesn't seem that hard to understand on the outside, so I didn't understand why I couldn't get a grip on it. For me I think I didn't understand why you had to use brackets and when you had to parentheses. It really confused me and for the longest time on my homework I simply stuck every notation with a bracket. Then a friend of mine was helping me and as she explained to me how the one problem worked it hit me. That when you are including a number you need a bracket and when you don't you place a parentheses.
Another thing I found sort of difficult was knowing when to switch the notation. At first I didn't comprehend what Mr. Jackson was talking about when the notation might change when you divide functions. It did not make much sense to me at all. I just thought that the notation would remain the same for all of the problems. It had me constantly worried for the test because I thought if those kind of questions are on the test I am sure  to be doomed.  Then as I began looking at the answer to the notation I began to understand when I needed to change the notation. It was like a click in my mind. I finally understood interval notation and even began to really enjoy doing problems doing interval notation. For me that was the hardest thing to learn for this unit.
