About this product

Product Information

The HP 35s scientific calculator provides professional performance for educators and business people by offering a range of highly attractive features combined with an easy-to-navigate interface. Both reverse Polish notation and algebraic entry-system logic in this calculator provide the majority of its power and accuracy. Its versatility, however, comes from 100 built-in functions, making calculating logarithms, inverse functions, and exponentials a simple task. Boasting a complete library of conversions, along with 42 built-in physical constants, you can also simplify most physics problems. With a memory of 30 KB, this calculator is also designed for reliability during those heavy workloads. If you make a mistake while entering data, the device contains edit, undo, and delete options that allow you to correct typos and produce accurate results every time. Around 800 independent storage registers also let you store equations for later retrieval to use in HP Solve.

Yea, RPN!
For years I used ALG calculators, and still do for simple tasks. The cheap, but functional Casios and Sharps work fine and have all the power to perform what I need. After getting an HP calculator and becoming familiar with RPN, however, the others seem awkward to use, especially for anything even slightly complex. I'm always having to either put partial results in some memory location or filling the screen with parentheses. I have a couple HP48 series calculators and they are wonderful tools but they're big. I've looked for a small and inexpensive RPN calculator and the HP35S, while not nearly as inexpensive as a lot of low end scientific calculators, is at least small and light. It has great functionality, a fine, high contrast screen, crisp keyboard and looks great. I've never had any other HP RPN calculators except a 28c, which isn't any smaller than the 48. I see a few other older HP models, but they command pretty high prices sometimes. The HP35S is great so far so I am hoping it has the robustness of its predecessors. That remains to be seen.Read full review

Has Some Flaws
At first glance it seems like it would be a great calculator for those who don't want to use RPN but want a Hewlett Packard. I found the display very hard to read as it has a glossy cover on the LCS so there are lots of reflections. Also the digits themselves are made from oddly shaped pixels and appear fuzzy. The buttons are louder than the classic HP calculators which was always nice feature of older HPs. These make a louder click which can be distracting and feels cheaper than the HPs of earlier times. The HP 20S is less expensive if you find it has the features you need. It also uses algebraic input, not RPN.

Very good modern calculator with most of the appeal of the old HP-15C
For many years I greatly admired the classic HP-15C scientific calculator from the 80s and had wanted to buy one for some time. But they were always too expensive when they came up for sale second hand, plus compared to modern calculators the originals are very slow and the display is quite limited. Then when HP released the new Limited Edition of the 15C last year with a promised 100 times speed increase over the original and a recommended price tag of $100 it looked as though I would finally be able to afford one and it would as fast as a normal calculator. Unfortunately the whole stock was bought by a few retailers who immediately increased the price to two to three times the HP RRP making them still too expensive. This forced me to reassess what I actually liked about the 15C and wanted in a scientific calculator of this type. The RPN entry system, classic HP angled key style, ability to write and store programs and work in different bases were all important plus these days the ability solve equations and have a more informative display would be a vast improvement over the 15C. Hence I looked at other HP scientific calculators and found the 35S, which has all the above features and many more and the only drawbacks compared to the 15C are that it doesn't look quite as classy and is in a more normal portrait format compared to the 15Cs landscape. It also has lots of other advantages over the 15C, it can be used in standard algebraic or RPN modes, it has many more functions available, far more memory, various conversion factors and constants built in, a two line modern LCD display and is a much more reasonable price. So I bought a 35S and I am extremely happy with it. It is a complicated calculator and takes some time to get to know, probably even more so than the 15C since it has so many more modes and functions. In fact I would recommend that anyone who buys one should decide fairly early on whether they prefer to work in normal algebraic or RPN mode and stick with the one mode. Although it is easy to switch modes on the 35S if you try to use it in both modes for certain jobs it does get very confusing since the key entry for most of the functions is completely different in the two modes. A fair amount of time should be allowed to learn how to use this calculator, with frequent reference to the user manual, at least at first. In fact reading the user manual is pretty much essential with the 35S when it first arrives as there are so many functions and methods which are not immediately apparent from the keyboard and work in a different way to scientific calculators from other manufacturers. In conclusion I would recommend the HP-35S to anyone looking for a non-graphing scientific calculator and especially to anyone who wants a modern day replacement for the old 15C.

HP35s - an EXCELLENT buy!
I love the RPN notation on HP calculators. I have owned many since my college days and first learned the notation on my HP-35 back then. I've tried TI calculators with the ( ) keys but RPN is still more logical and easy to use. I was designing a recent tool and needed more than a 4-digit machine (my 35 gave up awhile back). I researched the latest from HP and decided on the 35s. It has enough scientific capability and the RPN feature I like. Now that I'm an owner, I really like how I can store several programs at once and even work directly with fractions like 2 3/8 + 5 13/32 = ??? The 35s does it automatically!! Multiple conversions, a good feel, keys big enough for adult fingers - the 35s has it all! For the few dollars it costs, this is the best buy in calculators!

Calculator is exactly what a needed and was brand new!
I have used this type of calculator for decades and you cannot buy it in stores anymore. My current calculator just died and I am so thankful that I was able to locate a brand new one on eBay. Thank you!
