 Wonderful Calculator August 20, 2010

3 years ago, in Calc 1, I accidentally left my TI-83 in the classroom, and was never able to find it again. I had a test, and needed something, so ran to the university's book store, and had to choose between this for $10 and some TI calculator for $40. They looked almost identical, and I wanted the TI, because I knew they were a good brand, but I was poor and had to "settle" for this one. I was worried it would be cheap and limited and I'd have to buy another more expensive one later.
Fortunately, I was wrong. This calculator is light, easy to use, and does everything I needed it to do. It is easy to read, responsive, aesthetically designed so that using it is enjoyable. It is a good size so that it is not clunky and heavy like the graphing calculators.
I used it for the rest of Calc 1, then all of Calc 2, and all of Calc 3, and Engineering Statistics, and Discrete Math 1 and 2. Now I'm using it for physics 1, and I was looking at it thinking "I should go 5 star review this thing"
I don't know what the guy who gave it 2 stars was doing to get it to fade and break, but I have given mine a _ton_ of use. When I was in Calc 2, I was doing math 10 hours a day (I'm obsessive) you can go look it up, I have over 700 posts on Math Help Forum (internet site, can't put URL's in Amazon reviews). That entire time, I was using this calculator.
Also, he is foolish to whine about the + thing not kicking out an immediate answer, this allows you to see the context of where you are, and to edit your calculation, you can go back and fix a mistake, you can modify it after you get your results (it remembers your calculation, you can peruse and edit your history). You can save yourself tons of work if you use this well, and have a record of what you've put in so you can double check your work.
My only complaint is that when dealing with irrational numbers, it isn't smart enough to simplify fractions. ie it can tell you that 20/25 is 4/5 but not that (20 Pi)/25 is (4 Pi)/5. Also, it considers negative to be different from a minus, which is weird for a while.
Other than that, it does everything I needed it to: lets you store values in variables, has combinations, permutations, modulus, roots, exponents, logs, can display in hex binary and octal which got it use in some of my CS courses, trig functions, can use degrees or radians or something else that IDK what it is, does sums (sigma), bitwise operands like xor.
It also has a lot of other stuff on it, that I don't even know what it is. Presumably used in some other fields, but the point is that this list is just the things that I used.
Anyway, I highly recommend it. It was a great price and it completely exceeded my expectations in every way.

THE BUTTONS ON THE CALCULATOR ARE NOT SMALL, THE BRAND BRINGS IT UP ANOTHER NOTCH.

I have this calculator for about 1 year and the paint of the digits have completely faded away.
Often when I push a button, the calculator does not respond.
When you push a calculation button twice, for example +, or first push - and then +, the calculator gives an error, while other calculators would take the last entered calculation button.
When you would like to see a subtotal, for example 3+5+8+ other calculators would calculate at every entry of the +. This calculator doesn't, so you have to enter = first and then do the rest of the calculation.

Absolutely top-of-the-line calculator for basic science courses. College-level physics, chemistry, biology, statistics--this works just fine. For more advanced math (say, 300-level and above) you may want to consider something higher, and, of course, more expensive. Great value for the money, and rock-solid plastic build!
