### ...And Tomorrow I Rest

So I just realized that I need to really work on my basic math. I was working through a probability text book and missed a few problems, not because I did not understand the material but rather because I had made a stupid subtraction error. This mostly happens when I have to evaluate definite integrals. Really I don't have a problem with integrals (I find integration more interesting than differentiation but that is not the point), I just do not like having to actually plug in the limits to evaluate them. The main reason is because I sometimes make a mistake with the subtraction and this throws off the whole answer. Really I guess I just need to be more observant.
I finished reading and working through the book "Probability for Risk Management" a few days ago. In my personal opinion it is a good introductory book since the problems are not all that difficult and the authors do an excellent job at explaining the material. The hardest part for me was having to just accept some of the formulas on faith. I have just gotten accustomed to reading math books a theorem is stated and in the ensuing lines there is a proof. However, even though they did not provide proofs for every formula they did site other works where one might learn more about the particular topic and most likely find a proof.
Currently I am working through the 2005 ACTEX study manual. The first four sections were basically review for me since they covered some set theory and counting principles. The set theory stuff was mostly intuitive while the counting stuff was easy since I have been doing it since junior year of high school (and the problems I encounter then were much harder than the ones in the book). I did however, manage to get to challenging material. I even looked at a few of the practice exam problems to get a hint of exactly what I am in for. I think that was the biggest reality shock/ego killer I have had this year. Looking back on it I am relieved that I did that, so now I know just how much of a joke the exam isn't.
Linear is going smoothly. Honestly I don't see why people are always telling me it is so horrible. We just finished chapter 1 in class and none of the material was really taxing. I am about half way through chapter 2 and still nothing too bad. Right now I am contemplating if I should actually even take the number theory class in the fall. If I don't I will take Advanced Calculus 1 instead. I have arguments for whether or not I should take either class. However, there is no way I will take them both because one alone will be enough work since I have not taken the Intro. Number Theory class and from a reliable source and a few professors the Adv. Calc. is hard and time consuming. O well I am sure I will think of something by the time I need to make a decision.
