Review: The HP-50g Graphing Calculator is a great product once user understands RPN - The HP-50g Graphing Calculator is a great product once user understands RPN. To facilitate this education, please purchase the HP-50g Tutor Book and DVD (extremely helpful) available from desertcart. This calculator has the 100% correct feeling at the keyboard buttons. The HP-50g has just the right tactile feel and resistance and keyboard buttons does not contribute to finger numbness over time. The HP-50g has more science and engineering functions and more graphing features than many TI and Casio graphing calculators that are also higher in cost. The HP-50g graphing calculator is one of very few calculators capable of accurately sketching three-dimensional graphs. This is a perfect calculator for Reverse Polish Notation and Reverse Polish LISP programming of the very large, long, and tedious mathematical equations. The RPN format helps the user to get that answer faster and that answer can be given in more than one way without re-entering the equation! The Texas Instruments TI-89 Titanium and their TI Nspire CX CAS graphing calculators cause the user to "navigate" menus to seek out that single elusive function. At times, the TI user is loss between the keyboard buttons as the layout is not that intuitive. With the HP-50g the key buttons legend are printed with poor contrasting color background, but at least the user will easily find and access the features in a more intuitive way because of HP's layout and consistent key button scheme from generation to generation habits. User programming on TI calculators remind one of the days of the TI-55 II where the user must make entries with Algebraic entry system (more like BASIC computer programming language). User programming the old TI-55 II step by forgetful step (ah gee where am I), was it at step 09-22 or was it 22-90. The HP-50g is more user friendly for me even though this is just my second RPN calculator. User accessibility is crucial for technical fields. HP-50g makes it practical and visually easy in a gray scale display that does not distract the user with all the menus and colors. From the technical side, the HP-50g is a superior calculator with a ARM Holdings(UK) HP licensed ARM-9 203 MegaHertz de-clocked to run at 75 MegaHertz for compatibility to running legacy HP-48/49/50 software. The user can run older programs from the previous generation HP calculators. The HP-50g has a system BIOS that is user upgradeable. This is the Pilot's choice for quick complex digital mathematics. This is also the automotive designer's electro mechanical engine analyst. HP-50g's user programming support has no peer, and behaves better than most calculators. Been deploying and implementing calculators since A.D.1974 and the HP-50g has more user access to the firmware and hardware of the product than any other computation instrument in the handheld calculator market. For the practical user that wants to just run the HP-50g in everyday engineering, scientific, and advanced math equations at work, this calculator is more than sufficient for any task. Friends ask about it, family members want to trade their calculators for this HP-50g product, and professional folks want even more from this product. The other brands of new graphing calculators also have a long learning curve. Today there are computers and mobile devices that also perform a few of the 2,300 functions of a HP-50g calculator, not do it well. This is one dedicated, compatible, reliable, accessible, and affordable Engineer-Scientist-Mathematician-Three Dimensional Graphing calculator. This is a quantum leap away from even the fabled and legendary calculators of the previous generations. There is no other calculator that comes a "distance second place". The HP-50g Engineering, Scientific, Advanced Mathematics, Three Dimensional Graphing calculator works well like a vintage reliable Breitling Pilot Chronometer, like an accurate Fluke Multimeter, like a precision Tectronix eight channel oscilloscope with digital capture, like a forward looking Celestron Schdmit-Cassegrain 14inch folded lens telescope, and it becomes the best part of a professional toolkit like the Leatherman Wingman titanium and cubic pilot's pocket knife. The HP-50g calculator is the dedicated all purpose fast calculating device for the poly-disciplined technical professional. The HP-50g calculator is easy enough to learn that family members have permanently burrowed this new purchase. Will now need to order another HP-50g calculator. This product is superior to family's HP-19b II+, HP-48SX, TI Voyager 200, TI-98, TI-92, TI BA-II Pro, TI-89 Titanium, TI Nspire CX-CAS, HP Prime, Casio Prism, Casio FX-9860 II+, HP-12C, and certainly easier to learn then Mathematica, Maple, and MathCAD. Absolutely taken the HP-50g calculator along for the projects and to the job sites. Review: A very affordable and incredibly useful device - GENERAL: The HP50g is a recent purchase I made because I just started Calc III in college. My major is Computer Engineering which will require differential equations and physics I & II. I bought the 50g because I needed something capable of handling things like vectors, 3d shapes, equations and formulas that could be saved (easily), with the added hope that the CAS was moderately capable. I'm a firm believer that homework, especially math, should be done with pen and paper so that one truly understands the logic behind the work, but, I don't want to get a lower grade on a test because I made a silly mistake, so I had hoped that this calculator would be able to provide me with a way to check my answers on tests and to make homework easier by providing ways of experimenting with the equations easily. CAS: The cas is really good. It does everything I could hope for. All of the functions (derivatives, integrals, double integrals, and limits) can be solved numerically or symbolically. The point that surprised me the most was speed. I've used some CAS on computers (IE sage and matlab) and I expected the speed on a handheld device like this to be much slower than it actually is. GRAPHING: Graphing is much different than the method used on a TI-83. The 2-d function gaphing in the "Y=" form is still the same, but the parametric is much different as are the availble functions, but, as I get more accustomed to the calculator the more I like the method employed by the 50G. For one, it allows one to easily make calculations on the x/y/t variables. Instead of having to hunt down the function and enter a value to make a calculation on the result like on the TI, the HP has a single soft-button that puts the present variable values on the stack. This is very nice. The HP has a "conics" mode for graphing 2-d conics sections without having to solve the equation for Y. This is very nice, even in calc III where the conics are in 3-d, if you set one axis variable to zero and plug in the remaining values, you can quickly see what a 2-d slice looks like. RPN: At first RPN mode seemed really difficult, but the fact that as you enter values (which can be symbolic) and operations, being given an intermediate value is amazingly useful to double check your entries/work and having the result left to be acted upon again makes doing complex calculations MUCH easier. FUNCTIONALITY: The availble functions, constants, libraries, and customizability are all amazing. I love the ability to make my own soft-menus with the functions I need readily accessible. The ability to store my own defined functions is very nice, especially in classes like physics where I need certain equations over and over again. The organization of the machine is done really well with the most commonly used functions readily accessible and a searchable catalog of other functions. OVERALL: I would reccomend this over any of the other calculators I have used (Ti-89/nspire). The advanced functions are not really needed until one hits calculus. Id say that in all honesty, one could do absolutely fine with a ti-83 through most college level math classes and definately in high school, but in the higher math classes as well as physics, the functionality is so nice that I'd say it makes the work ten times easier to do. I wouldn't reccomend this to someone who doesn't plan on taking much math past college algebra, but, if your a major/professional in a math intesive job, this is a must. With the price being what it is on desertcart, I'd say it blows away the competition. My only two complaints are the included documentation and the keyboard. The keyboard is tough, nothing as good feeling as the TI machines. The documentation is completely lacking, but the internet has everything you could need or want. HP does have several full manuals availble for download which make up for it, but I would like to have a hard-copy of one included. ## Features - New display upgrade--the new HP 50g display features a 30% increase in usable space over the HP 49g+ - New powerful SD card slot allows you to format your card right in the calculator and expand memory - Massive 2.5 MB total memory--512 KB RAM plus 2 MB flash ROM for performing future upgrades** - New larger equation library and 2300+ built-in functions--ideal for both professionals and students - The choice of efficient RPN, Textbook or Algebraic data entry ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000GTPRPS | | Batteries | 4 AAA batteries required. | | Best Sellers Rank | #181,790 in Office Products ( See Top 100 in Office Products ) #63 in Graphing Office Calculators | | Brand | HP | | Color | Black Face | | Customer Reviews | 4.7 4.7 out of 5 stars (1,388) | | Date First Available | September 9, 2004 | | Is Discontinued By Manufacturer | No | | Item Weight | 9.6 ounces | | Item model number | HP50G | | Lines Per Page | 8 | | Manufacturer | Hewlett Packard | | Manufacturer Part Number | HP50G | | Material Type | Plastic | | Number of Items | 1 | | Product Dimensions | 7.2 x 1 x 3.5 inches | | Size | AB1065 | ## Images ![HP 50g Graphing Calculator - Image 1](https://m.media-amazon.com/images/I/81BwuUGy-3L.jpg) ![HP 50g Graphing Calculator - Image 2](https://m.media-amazon.com/images/I/717DQ9Oag5L.jpg) ![HP 50g Graphing Calculator - Image 3](https://m.media-amazon.com/images/I/6198t6aY6FL.jpg) ![HP 50g Graphing Calculator - Image 4](https://m.media-amazon.com/images/I/71To5CylmgL.jpg) ![HP 50g Graphing Calculator - Image 5](https://m.media-amazon.com/images/I/613dlgwR30L.jpg) ## Questions & Answers **Q: Programmable ?** A: Extremely programmable. Very rich programming language. **Q: Does anyone know if there is compatibility with HP41C programs? My old 41C died... sob...** A: Very little compatibility. The object-oriented design makes programs look utterly different, although there's still a stack, and you can still use RPN, so that may give you a leg up. The stack is of indeterminate height instead of XYZT. There's no special alpha register, so alpha output needs to just become an alpha object in the stack. Nonetheless, I rewrote a couple of HP41c programs for HP48g and was happy with the result. Then I rewrote them again for HP33s/HP35s, which are sort of like HP11c and HP15c, or HP41 without the alpha register. By the way I had terrible luck with HP50g. My first one broke for no apparent reason, and I sent a second one back because the battery compartment wouldn't snap shut. On a physical level, these things are crap. **Q: Why is this product so much more absurdly expensive than the HP Prime itself?** A: The HP 50g can do things the HP Prime can not do because the HP 50g has the RPL language that uses a stack; which makes the HP 50g much more powerful than the Prime in many respects. Also, the HP 50g was discontinued by HP in 2015. In November 2020 I purchased two new HP 50g's for $500 each, one used for $200 and another used for $135. I need these calculators for my research. The HP 50g is well worth whatever you pay for it. **Q: Can the font size be changed on the HP 50g?** A: Yes. It has 3 font sizes (8, 7, 6). To find, press the MODE key, then the DISP soft-menu key (F4), then the CHOOS soft-menu key (F2). ## Customer Reviews ### ⭐⭐⭐⭐⭐ The HP-50g Graphing Calculator is a great product once user understands RPN *by V***T on July 29, 2014* The HP-50g Graphing Calculator is a great product once user understands RPN.

HP does have several full manuals availble for download which make up for it, but I would like to have a hard-copy of one included. ### ⭐⭐⭐⭐⭐ Worth the investment *by A***R on October 11, 2013* I am actually a computer science and mathematics student so getting a fancy calculator like this was a no brainier. I've owned the HP 50g for about a year now. The HP 50g comes with a rich mathematics library already built in - but what really sets it apart is its rich programming environment. With TI calcs you only get TI Basic and assembly (if you are lucky) but with the HP 50g you get reverse polish lisp (RPL) which is a very stack based language and was a little weird for me at first (I'm used to languages like C) but it turns out RPL makes mathy stuff really easy. In addition you get Saturn assembly (the original processing architecture of the HP calculator) however with a firmware mod you can tac on ARM assembly (the HP 50g is basically an updated legacy HP calculator operating system code base running in a Saturn virtual machine on top of a physical ARM core) and C which can be nice for building text editors and such. If you wanted to get your computer nerd on you can even over clock this calculator with the firmware mod. Plus on stock firmware there is a RPL environment and a Saturn assembler built in - as awkward as it is to punch code into the calculator you can code on the fly if you need too. There is a clunky workstation package for NT boxes but I find support under Linux just as good for building my programs and transferring them over the serial connection. I haven't really talked about reverse polish notation (RPN) which goes well with RPL, by default the calculator is configured to use algebraic notation which I find myself never using except maybe on paper. RPN is a stack based approach to calculating, it is actually how most calculators work internally anyways. Expressing things in RPN is great because it forces you to think about what you are doing in smaller bits so I find myself making less errors and also there is no need for parenthesis to enforce order of operations. I find that as of now (20131011) the HP 50g out classes any other calculator on the market in raw computing power - it renders graphs with very little delay at all. Other nifty features include an SD card slot - which unfortunately does not support the contemporary high density cards, but 256 megabytes is plenty of room to store all my programs on. I believe there is also an infrared based protocol suite for connecting to other HP 50gs and sharing data - which seems rather odd but who knows maybe you could write a program that lets you change your TV settings from your calculator. I would totally recommend this to anyone going into college - especially an engineering or science field of study - or anyone else who needs to crunch a lot of numbers. I also urge buyers to learn RPN, before I bought this calculator I was not a believer in RPN but after a year of use I find myself preferring RPN to algebraic notation, it just makes doing calculations easier. ## Frequently Bought Together - HP 50g Graphing Calculator - FitSand Hard Case Compatible for HP 50g Graphing Calculator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/1144727-hp-50g-graphing-calculator](https://www.desertcart.is/products/1144727-hp-50g-graphing-calculator) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-05-22*
