Amazon.com Review

Hewlett-Packard's HP 48G+ calculator can handle just about anything, and for a reasonable price. It allows you to enter equations the way they're printed on a page; construct graphs, plots, and drawings on a display 8 lines deep by 22 characters wide; and perform calculations from basic algebra all the way up to trigonometry and advanced statistical analysis. Best of all, anyone with the patience to learn some basic, object-oriented programming can take the device far beyond its built-in limits.

We had to throw out all of our typical calculator knowledge to use the 48G+, as it uses Reverse Polish Notation (RPN, also known as postfix notation). For example, instead of pressing 2 + 2 = to get an answer, you have to press 2 ENTER 2 +. Once we learned the basics, RPN made complex calculations much easier to enter, eliminating the need for parentheses in most calculations. Studded with buttons and crammed with labels, the keypad looks impossibly crowded, but the color-coded secondary and tertiary function labels are easy to find and decipher with a little practice. A row of buttons at the top is used to select menu items that are displayed onscreen, providing even more functions in a relatively small space. Ultimately, the 48G+ offers more than 2,300 functions, over 300 of them built-in formulas and scientific constants encompassing the spectrum of the mathematical and scientific fields.

Using the 48G+ for a few weeks made it clear why this series of calculators is so popular; they're easy to work with once the initial learning curve is overcome. A complete set of built-in formulas coupled with the calculator's programmability give the device potential limited only by its 128 KB of built-in memory. If you need lots of RAM, its upgradable memory makes the higher-end 48GX a better bet; however, the 48G+ has plenty of storage for all but the most demanding students and professionals. It also comes with an infrared port for communicating with other calculators or a printer, and a connectivity kit--available separately--allows you to link the calculator to your PC for downloading new formulas and other data. --T.

5 out of 5 stars Best Calculator.......2002-02-18

I started owning the HP 48S calculator 10 years ago when I was in high school. Been using it at Cal while I was there. Actually, almost everybody in EECS major owns an HP48. When the HP48G model came out, I gave the old one to my cousin and bought this one for myself. And I am still using it at work now. This calculator can do ALL the "calculatable" stuff and much more. Just try sin(i) or i^i or 200! (where "i" is the complex number sqrt(-1), "!" denotes factorial) on a calculator other than HP48/49, you will get an error. However, there is still many area that this calculator (or any other calculator) can improve on. One of the major one is doing the symbolic calculation--as in symbolic integration. But this requires much more cpu power than just a calculator. So I don't blame them for this. And as an added bonus, you can download thousands of freely available software to your calculator to make it into a PDA, remote control, play games or just expand it into a more powerful calculator(like calculating factorial of 1000).
Overall, I found this calculator to be nearly perfect. As a math or engineering student in any grade level, you should definitly own one of these. If you are thinking just to get pass your algebra class, than forget it! You won't even know how to add using the calculator before your semester is over.

3 out of 5 stars Disappointed.......2002-01-18

I am an engineering student and now see why my university recommends the TI-83. I'm sure the HP 48G has more features and is generally more powerful, but the user interface stinks. This is so hard to manipulate that I must carry a second calculator just in case I need a quick calculation. The RPN format is absolutly miserable and I have no idea why one would want this on a calculator. Another drawback is that the users manual falls FAR short when it comes to programming. The calculator falls even shorter and doesn't even have a If/ GOTO command for loop structures. If an engineer in training can't easily use this calculator, you'd better be a rocket scientist to expect much more. Unfortunatly I will have to buy a TI-83 to overcome the programming shortcomings, a move I should have made originally.

5 out of 5 stars Ugly, Slow Graphing but a Grand Machine.......2001-12-05

Every comment here is right.
1. This calculator can do everything but change the baby's Pampers.
2 It is S L O W E R [drawing a graph] than the class dunce.
3 It is the best graphing calculator for the money.
4 It is made really well and will be working for your heirs long after your in the graveyard [but do leave them the users guide]
5 It uses both RPN and/or algebraic input.
6 No-One whom I know uses all the functions of this calculator.
7 The review is almost scary nearly suggesting this is not a device for mere mortals. Hogwash, my grand nephew who is blessed with the same average intelligence as I has used this calculator in middle school

There is a grand debate: Texas Instruments calculators vs. H.P. Firstly, I am a H.P. user. No doubt, though, for most tasks the T.I. will be easier for most folks but for versatility, accuracy, durability and reliability, or if you are not IN a school which requires a T.I. you are better off with the Hewlett Packard .

To be honest this is not a 'take to class everyday'. if you are in high school unless one is doing some really advanced maths. Even for much collage maths this calculator is 'overkill'.

That written if you can use it, if it is not banned if you require a graphing calculator and have the time to learn how to use this one it is great, and one will find nothing as it for any price.

If you are new to HP or RPN buy a book from Amazon titlled 'jump start The HP 48G/GX by Adams and Potter ... [dont throw away the user guide for use later].

As an aside I loaned my 48G+ to my grand nephews 9th grade 'girl' and she likes it so much she has replaced her TI with it which suggests that I am in the 48G+ market, agan. [I triied the 49 but the keyboaard STINKS]

5 out of 5 stars My favorite calculator!.......2001-10-21

HP's line of calculators are *really* well done.
I've been using my HP48g+ for almost 2.5 years, and there isn't enough good things I can say about it! (Minas the lack of speed, due to a 4.3mhz processor)

The HP48 line of calculators present a scalable, fun, and neat product. There are so many neat things I've been able to do, such as change the TV channel, play songs, play games, and oh yes... do math!

If you are looking at the TI line, they are alright, but nowheres near as fun as a HP48. The TI's might have better hardware compared to the 48, but it's software smells! Take it's GUI for example, it has none! You punch in numbers and it calculates the answer!

My number one favorite thing about the HP calculator is it's softkeys... they make it so much easier to operate!
