Durable, high quality, sturdy, what you come to expect from the Melissa and Doug line of items.  My kids use this with the Rod and Staff math curriculum as an added manipulative to help them with addition and subtraction.

You better be into some serious mathematics if you want to tackle this book.  I'm not.

Nothing special about this calculator just a cheap standard version and that was all that was required, so it fit the bill for Math class. Good first step calculator which could help a student familiarize themselves better with with the usage and operation of calculator. Student's are going to need to be ready when those harder High School classes appear.

"I love spending $100+ on a calculator so I can do math," said no one ever.

It works.  I just hate math.

In Geekspeak, Graham Tattersall shows how simple math can be used to answer questions such as "How fast is a fart traveling?" and "How much does your head weigh?" Tattersall relies on estimates and back of the envelope-type calculations to keep things simple, so anyone who can add, subtract, multiply and divide should be able to follow his reasoning. (Integration is mentioned once, but only in parenthesis). He keeps his chapters short so as not to lose the reader, and the corny jokes are kept to a minimum. Highly recommended for those who appreciate math, or those who want to appreciate it but are intimidated.

When I learned that this was the required book for my introductory data structures class this semester, I was somewhat worried by the large number of very negative reviews I saw it had received here. However, during the first class meeting, the professor made a point of instructing us to get the third edition (published in 2004), explaining that the differences between the second and third editions were significant.

Judging by the older reviews below, he was right - the book I read seems to bear little if any resemblance to the one denounced by the other reviewers. I found it clear and readable, though it was rather basic and dry. But then, I wasn't expecting great literature - this is a introductory compsci textbook, after all. Though it could be dull at times, it generally managed to get its information across clearly, which is all it needs to do. There were some typos, of course, though probably not more than should be expected to accompany such a major revision. The book's main flaw was an index that had essentially no relation to the actual text itself. A corrected index is available at the book's Web site.

In terms of organization, Goodrich and Tamassia start off with a brief introduction to Java, object oriented design and a brief and very basic discussion of running time and asymptotic analysis. They then work their way through basic data structures and abstract data types - stacks, queues, vectors, lists, trees (general, binary, and binary search), priority queues, heaps, dictionaries, hash tables and graphs. They discuss the structures' purposes and major operations, analyze the operations' running times, and include decent, heavily-documented Java implementations of some of the structures and methods. They also do some stuff with algorithms, though generally nothing very complex or sophisticated. I used this book in an introductory data structures course at a liberal arts college, which managed to cover pretty much everything in the book with little difficulty.

There are a lot of exercises at the end of each chapter. Goodrich and Tamassia divide them up into progressively more complex "Reinforcement", "Creativity" and "Projects" sections. My instructor preferred to assign problems and programming assignments of his own creation, though, so I don't know how helpful or useful the exercises in the book actually are.

All in all, it seem Goodrich and Tamassia noticed the sort of reviews the earlier editions of this book were getting and took steps to correct the many problems they had. I expect that if you have to use the book in a data structures course, you'll find it at least reasonably clear and generally acceptable. As long as you're using the third edition, that is.

Please, just let the computer or calculator do the math. Why does your mind need to do it other than to give this flub money?

This calculator comes with color display and most of the tools that TI calculator would have except that it'll become useless once you have to deal with multi-variable calculus & linear algebra (yes, it could perform matrices, but it lacks the tool to solve Gaussian & Gauss-Jordan elimination a.k.a ref & rref). If you don't plan to take higher math classes, yet need a cheap & functional graphing calculator, this gadget is for you, otherwise get TI-89.

In "Mathematics for the Million," Hogben takes the reader through the entire evolution of mathematics. He begins with ancient farmers whose meager math skills consisted of knowing the values 1, 2, 3, and  "more than three," and shows how these skills grew out of  necessity as societies became more complex. Hogben's goals are twofold.  First, he means to educate the average person so that math won't remain the  esoteric domain of academics. Second, he means to demonstrate that  mathematical advances occur when math is used to solve real problems, and  not when it's used as intellectual entertainment for an idle leisure class.  Hogben succeeds on both accounts, and in doing so he (very subtly) develops  a theory which anticipates the structural Marxism of the '50s and '60s,  including the work of Louis Althusser, Herbert Marcuse, and Jurgen  Habermas. But Hogben's real magic is that he makes all this accessible to  anyone: Even those with no math background at all will be doing calculus by  the end of the book, even performing calculations to measure the Earth's  circumference or the distance to the moon. Never has such an opaque subject  been as lucid as in "Mathematics for the Million."

This is a very general math outline that simply builds from basic to complex mathematics.  It lacks almost all of the colorful visuals, word bubbles, and examples of the usual math textbook.  In fact, it's not really a textbook at all.  It doesn't teach on the level (ie- 4th grade, 6th grade...).  It simply starts with the number line and builds concepts from there.  It contains a lot of math knowledge, but has all of the redundancy of annual learning and re-learning stripped out, so you have to know how to use it properly.  I'd recommend using it a few months before taking a major placement test (SAT, ACT, etc.) or if you are going to teach math to someone (your children or as a new teacher) just to wrap your mind around all the math concepts at once and build them in your mind in a logical sequence.  I wouldn't recommend using this book on a young student or new learner of math unless you are using it as a tutoring reference--it's not made to motivate students--it's made to instruct the person earnestly seeking to learn math properly.

This book is to pure maths what Knuth's Art of Computer Programming is to computer science or Feynman's lectures are to physics. If I was to be a castaway on a desert island, and was permitted to take only one book on  mathematics, this is the one I would choose. I cannot recomend it too  highly.

For doing any sort of fast programming or deep mathematics, I've been using Mathematica since the early 1990's. My first usage was on a Mac Plus, calculating the determinant of a large matrix.

Obviously, both computers and Mathematica have improved since then. The big draw for me has been the thousand of online examples of many types of math, at *.wolfram.com, with * = (demonstrations, mathworld, library). For many areas of math, working code will be findable at one of those three sites.

Also, that code will often be short. Go to the Wolfram Demonstrations Project and give it all a test drive, play around with the interactive examples, and take a look at the code that generates them.

Computers today are roughly a billion times more powerful than a few decades ago. That allowed the teenager Neil Bickford to use Mathematica on the Minsky Circle problem and find hundreds of things that have never been seen before. Any math problem subject to computer attack that hasn't been looked at in the last decade basically hasn't been looked at seriously. Myself, I made the mistake of looking at the Mrs. Perkins Quilt problem, which deals with dividing a square into smaller squares. With billions of times more power than the last people to look at the problem, I couldn't help but greatly improve the known results.

Highly recommended.

This calculator doesn't even follow any basic math hierarchy principles.  A basic calculator should be able to work with addition/subtraction and multiplication/division by math hierarchy.

For example, multiplication/division is higher order than subtraction/addition.  The operation 5x5 + 6x5 if following math hierarchy, would result in 55.  Instead, by not following hierarchy, this gives an answer of 155.

If you think this is not a big deal, it is.  This means to perform the first part of the operation, you would need to store the first half of the equation (25) in memory, then perform the second part and then add memory to the result.

No only is this not good for someone learning math, but adds ridiculous steps to the process.
And then there is no "clear memory" button.  Another ridiculous operation is clearing memory.  You actually need to add the opposite sum to the memory to clear it.

Another no go is the battery.  This unit is not made for battery replacement.  You would probably break the case trying.

There is a generic set of instructions for all the basic TI calculators, not of which explain the 503SV, no battery replacement instructions, and the math examples given are a basic subtraction/addition operation and a basic multiplication/division operation.  Of course, no examples given showing the flawed hierarchy.

This is another piece of Chinese junk, and shame on TI.

If you want to understand Generating Functions, you have to have a good grip on the mathematical results relating to sums of sequences. The only other work that compares to this one is the AMS's "Real Infinite Series" by Bonar. I believe the "Golden" series was originally a British series published in the 40s or 50s. They all begin with atomic definitions and simple results on series that gradually build up to complex results. Its an older way of learning math, primarily by doing increasingly more difficult problems. I like the approach. I think the "Golden" series of books was eventually published by a publisher of math texts in India. To purchase this work I had to order from an Indian distributor. It's cheap work with a low standard of printing but a very high quality of content.

In spite of the seeming easiness of using this calculator with having it display the integral signs, etc., there's many different settings to switch between; this can prove frustrating. Generally speaking, by the time you need a calculator with this many functions, you'll be using a graphing calculator. The only reason I bought this was because one of my professors required you to have a non-programmable calculator; this serves it's purpose well. Don't think though because it can integrate it's powerful; most integrations take at least several seconds.
