They usually don't come with zipper cases.br>If you let us know when you order, we'll include a zipper case with the unit.br>Thank you.
The reason for this, I believe, is that the calculators are sold by two different vendors (who are both fulfilled by Amazon). They're both the same thing, in other words. HP35S is the same thing as HP35S. If you look at the images closely, you'll notice that both options are programmable. It's worth noting that the top row's left four keys are programming functions.
It is packaged in a protective case.
Yes, the calculator comes with an instruction booklet. Because I didn't program mine, I'm not sure how much information there is in the operating manual about programming this calculator. You can inquire directly with HP about their technical support.
Selected User Reviews For HP 35S 35S Programmable Scientific Calculator, 14-Digit LCD (HP-35S/B12)
This is the fourth time I've used an HP RPN pocket calculator. My first car was an HP 45, which I bought in 1974 (and which cost more than my first car). Although not programmable, this device is extremely useful. It still functions in some ways, but only when plugged into a wall outlet. My second computer was an HP11C, which I bought in 1980. In every way, this calculator is fantastic! It still works, but I have to be very careful with each keystroke because the buttons occasionally fail to register. Its integration function/algorithm, on the other hand, does an excellent job of simulating analytical solutions. That was not the case with my third calculator, a HP 32SII that I bought in 2001. Its integration function was faster and typically 10 less accurate than the HP 11C (i. e. , by repeating the integrals and comparing them to the analytical solution). The buttons on the HP 32SII have completely failed. They just don't work any longer. So. This new HP 35 S has been installed in its place. Surprisingly, the integration algorithm is terrible! Breaking down an integral into smaller and smaller parts (and then adding the solutions together) gets you closer to the analytical solution, but. What a pain in the neck! Another issue is that it is a hybrid of RPN and algebraic (i. e. Philosophically, he's all but a sellout). Only algebraic programming examples are provided in the owner's manual. This wouldn't be an issue if the RPN programming protocol used by previous HP devices remained unchanged, but it didn't. I've had to fiddle around with the settings to get my programs to work, as the manual isn't very helpful. I'm glad I still have my 11C, but after 39 years of service (more lightly for the last ten, but hey! ), it's time to retire. ), it will eventually fail completely. So here's my message to HP: Bring back the 11C, which is made to the same high standard as the original! In the meantime, I'll keep plugging away at this 35S, unsure of the quality of my integration results.
My first handheld electronic calculators were TI scientific calculators, but I really wanted HP due to the RPN and overall quality. In 1978, I received my first HP, an HP-100. 67 programmable calculator (which I still have but can't use). In the year 1987 (? ) I was given an HP-compatible computer. I still have 15C in my possession. and continue to do so. It's an excellent calculator that HP no longer produces. I was looking for a second (or third) RPN calculator when I came across this item on Amazon. I decided to order one after reading the reviews and doing some more research. It's very nice, especially if you're used to HP-branded products. 15, HP- 67, HP- 41, the primary functions of this calculator have a very low learning curve. If you're in need of HP's financial wizardry, Stop right here and get one of those, 12C. Aside from that, this calculator is excellent for scientific and mathematical tasks. Unlike the other HP calculators I mentioned, this one also handles fractions as fractions (if desired), has a better way of displaying imaginary/complex numbers, and has metric conversion capabilities. > It also has a lot more storage and can convert US units (which is admittedly only useful in the United States, or in other countries attempting to understand our baffling measurement system). It feels a little less expensive than older HP models, but its keys are more comfortable (to me) than the flat screen on a smartphone calculator app. The device is also much lighter than a smartphone with a battery pack. It has a nice sleeve attached to it. a case in the style of the HP- 15C. This device works in Algebraic mode, so it's still useful if you need to loan it to someone who doesn't understand RPN (or if you don't understand RPN yourself). Non-profit organizations, on the other hand, may have better options. If you don't need RPN, there are RPN calculators. It's not overly difficult to use for numerical base conversion (binary, octal, decimal, and hexadecimal only), but it does necessitate some reading. There are a couple of additional keystrokes that aren't immediately apparent. br>br>In summary, it's a good RPN calculator that will be simple to use for HP fans, but not so much for others. For what it is, it is reasonably priced. It's trivially easy to use for those familiar with RPN for basic scientific calculations, but for other functions (base conversion, equation solving, programming, fractions), you'll need to consult the (excellent) online manual or another online resource.
I was spoiled by my 48 GX, but I needed this one for the PE exam. I'd like to point out that there is no indication that you've reached the limit of your stack. It will provide you with an answer, but it will be incorrect. Unless you're used to the 48 GX's much larger stack, this is unlikely to be a problem.
Learn it! In addition, the keys are pleasant and upbeat. HP genius, as usual. It's simple to get up and running, but understanding all of the features will take two PhDs. But don't worry; it can also do what you're used to. br>br>RPN is a unique syntax that eliminates any ambiguity about what comes first in operations or what goes with what. There are no parentheses here. Yet you can type in the most complicated expressions, get your answer, and keep going, nesting equations and appending the answer to the current result value, many layers deep. This is something you should definitely learn. You won't be able to return.
Yes, it's lighter weight, and the keys are decent compared to others, but they're not as good as the old HP, which I knew going in based on the reviews. And, perhaps it's just my memory, but there are two things I don't recall about the older calculators (I had a 28S that eventually wore out - a long time later - a 32SII that was removed due to a hardwood floor - In retrospect, I'm still kicking myself for not trying to fix it). br>1) When you press Enter, the value is added to the stack, but the current entry register is also updated. Why? On the 28 (you only see one line on the 32), I swear it wasn't like this. It's annoying, but not unbearable. 2) Undo is limited in what it can undo. Again, at least on the 28th, I could swear that this undid the previous operation, restoring the stack to its previous state. Neither of these factors affect my opinion - The product is exactly what it is, but at a lower cost - Sadly, yes. I got it because I was finally sick of not having RPN when I needed a calculator for quick calculations (especially when I already had a lot of windows open and didn't want to open another one). But I thought I'd bring them up because they're odd behaviors. If my memories are incorrect, I would appreciate hearing from you so that I can update my review.
