HP F2229AA#ABA 12c Financial Calculator Review

Average Reviews:

(More customer reviews)I happen to buy this product directly from HP. I had it for two weeks and the interal display broke. Called HP tech to find out about getting it repaired, and was told that it was my fault that it broke, and that it was not something that could be repaired, bottom line I was told I had to buy another at 160.00. I have had a complain into Hpheadquarters for about a week now and have not gotten a response. Next step is the better business bereau.

CASIO FX115-MS SCIENTIFIC CALCULATOR WITH 300 BUILT-IN FUNCTIONS Review

Average Reviews:

(More customer reviews)Have used Casio scientific calculators throughout my life. I've had my 115MS for some three years now. I use it for electronics design and I've been constantly amazed at how every special function I ever need is there. Binary/hex/decimal conversions, engineering conversions including metric prefixes (kilo, micro, nano, pico etc. which I find simply indispensable), complex numbers, etc. The CALC function is particularly useful when I want to see how different values will alter the answer to a formula/equation.

One thing that peeves me though is that it takes three keystrokes to store a value in memory (variables). That's cumbersome.

Overall this inexpensive calculator gets a three thumbs up from me. If Casio makes an exact model with added programmability, I think it just might be the perfect calculator for me.

Hewlett Packard HP6S SLR Solar Scientific Calculator Review

Average Reviews:

(More customer reviews)This calculator could be one of the very best scientifics sold by ... but it is not. In fact, it is not best for the price, even.
The best scietific is the Hewlett Packard 32Sii but it costs near to 60$ U.S. which means they are not a `give to the kid to take to school' item. Being the `nerdly grand unki' I get to help all the school-agers with their math homework. I agree with the math teacher, here, that this is an `O.K.' calculator but given the present shipping-cost addition to this calculator I suggest one would be better off buying the algebraic entry Hewett Packard 30S or [even] the Texas Instruments 34 II.
Somehow the `RPN' or postfix entry system is thought of a `hard to learn'. The kids here all use it, there are several Java based RPN calculators on the WWW but this calculator doesn't have RPN. If it did I would buy several. Without RPN I cannot even highly recommend this well built fairly easy to use [but no kid likes the siff rubber keys, calculator.

You can perform quick and easy conversions with hexadecimal, decimal, octal, and binary bases, and enter data in algebraic notation, just as you would on paper.

HP HP48G PLUS Graphic Calculator Review

Average Reviews:

(More customer reviews)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 Iloaned 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]

Touch-Screen Graphing Calculator Review

Average Reviews:

(More customer reviews)I have owned numerous calculators by HP, TI, Sharp, Casio, etc., but this new Classpad 300 Plus that was just released a few weeks ago with Casio's latest operating system (OS 3.0) and Classpad Manager 3.0 is just fabulous. It is now in common use in Europe, especially in Germany and also in Australia and in New Zealand. If you purchase(d) the version with OS 2.0, you can still upgrade electronically to the newest version using the Classpad Manager Version 3.0 directly which has a number of very nice new features/functions. This calculator should also be in common use in the USA as well, but regrettably the financial dominance of TI in our marketplace (and the impending arrival of the new TI NSpire calculator) make the likelihood of its acceptance very soon quite small, unless people like myself write reviews like this to promote educators to really get involved with this new product. The real advantage of both the Classpad as well as the TI NSpire calculator (which is not a pen-based product like the Classpad) is the great software that installs on PC's so that a complete emulation of its operations is possible even without the calculator being physically available. It addition, however the Casio (OS 3.0) will do now do Dirac Delta functions, Heaviside Step functions, Fourier and Laplace Transforms (including Fast Fourier Transforms, i.e., FFT's), First order ordinary differential equations, financial analyses, and of course it already performed complex number analyses, etc.
The operating feature on the Classpad that appeals to me the most however is the pen-based drag and drop operations using the Computer Algebra System (CAS) and the interactive menu between each of the numerous types of submenus on the device. Any operation worked on in one area (Graphs and Tables for example) can readily be copied and pasted into another area (Statistics, Spreadsheets, Sequences, etc) just to name a few of the numerous possibilities. The E-activity submenu on the Casio supports presentations to an audience and is the analog for the Classpad of the TI NSpire's 4 screens of information that can all be put on to a single screen at once (analyzing a problem using a geometrical representation in the form of a drawing or a picture, a word statement of the problem, an analytic or numerical equation solution and a graph of the results). Finally, the results can all be ported back and forth and printed/stored, etc. between the Classpad Manager software/emulator and the calculator itself which is simply fantastic to use. I have had this for almost a month now and I am just begining to appreciate what it can do for me daily in my work as a scientist. If students get exposed to these devices in a late middle school curriculum and beyond (after they first master many of the basics of mathematics and science), in my opinion they will want to continue to grow into math and science in their later years and become excited leaders in science and engineering that this country has been famous for having for most of the last 60 years.

HP 17BII Financial Calculator Review

Average Reviews:

(More customer reviews)One of the best features of this calculator is that the calculations (i.e. present value/future value calculations and basic mortgage payment calculations)are menu driven using a series of buttons at the top of thecalculator.You simply input the data per the associated input button.Inaddition, this calculator is a lot easier to use than the 12B which is thestandard in the leasing industry.The 17B version allows you to input yourdata in a straight forward fashion rather than the "reverse" datainput method of the 12C.HP also did a good job with the instructionalbooklet you receive with the calculator.The booklet gives you numeroussample problems and does a good job of highlighting the capabilities of thecalculator in an easy to understand format without all the technicaljargon.I wouldn't be without this calculator.

Product Description:
With the HP 17BII financial calculator, you can perform more than 250 business and statistical functions from wherever you happen to be. You can calculate loan payments, amortization, interest rates and conversion, internal rate of return, net present value, bond price and yield, depreciation, and percentages, to name only a few.
The bottom line on the two-line display shows the menu labels for the five major menus in the calculator: Financial, Business Percentages, Statistics, Time Manager, and Equation Solver. The menu keys allow you to shift between functions. The top line shows the numbers or letters you enter and the resulting calculation. Each menu has subfunctions and built-in variables for greater complexity. A beeper sounds when you press the wrong key, when an error occurs, or when you are late for an appointment.
The HP 17BII has 8,000 total bytes in RAM (6,750 bytes plus 1,250 for your built-in variables). You can monitor the available memory (both in bytes and percentages) by pressing shift-MEM. The calculator retains current functions until you press "clear data." If you accidentally shut the machine off, just turn it back on and your calculation will reappear. After 10 minutes of nonuse the calculator turns itself off, but your most recent information will still be there.
The HP financial calculator interfaces with an HP infrared printer (sold separately), allowing you to print tables, lists, and payment schedules whether you are--in a meeting or on an airplane.
A protective cover is included to keep your calculator dust-free. Batteries are already loaded, and the calculator is backed by a limited one-year warranty. --Dana Van Nest
