Great RPN calculator for the PE

I recently used this for my PE exam and it served its purpose very well. My brain simply doesn't work in algebraic anymore, so I had to get this RPN calculator. You'll want to get this before you start your studies so you can get used to the location of all the keys and beware that this only hold 4 rows in the stack. Anything above that is nixed. It's also more of a pain to clear all the stacks.... I had to just enter "0" and then hit Enter 4 times to do it quickly. My last gripe is that it doesn't use AAA batteries, but I did find them readily available at the battery center at walmart for pretty cheap. I'm debating on whether to keep it or go back to my 48G.... I'll see what that PE score is first ;) If you're PE bound... good luck!

Reverse Polish Notation

While the hp 33S is capable of both Algebraic and Reverse Polish Notation (RPN) entry, it is the capability of RPN logic that gives this Hewlett Packard Calculator its extraordinary calculation ability. With the automatic 4-register stack, a feature since the beginning of RPN, calculation results are shown as soon as a function button is pressed. It is in this manner that the results of all intermediate calculations may be viewed. Beside being a standard calculator, the HP33S is programmable. It has numerous numeric-memory-registers in which to store data, as well as a fairly sizable program memory, and the numeric-memories are accessible under program control. It has statistical abilities and well as all the normal scientific and engineering capabilities. It also has the ability to work with fractions. In short, it is truly an extraordinary calculator. – Written by Michael H. KeehnRead full review

Hewlett-Packard HP-33S Scientific calculator

This calculator is the successor of the well known HP-32SII which was an evolution of the famous HP-32S. Compared to the HP-32S, the HP-32SII added algebraic, math and fractions support. The production of the HP-32SII stopped in 2002 and the HP-33S came out in 2003. The HP-33S is not a real HP calculator, it belongs to those implemented by Kinpo (one of HP's OEM). The memory has been increased to 32Kb compared to the HP-32SII. I would have prefered a more conventional and nicer keypad. Sincerly, except if you just look at the pure performances and features, I would recommend you a HP-32SII. If you have more money or accept to buy a second hand calculator, check at the HP-48G, HP-48G+ and HP-48GX family. You will not be disappointed.

HP 35S Calculator

A culmination, of sorts, of all previous mid-level HP calculators - released to commemrorate the introduction of the 'original' HP-35. All the functionality of the HP-33, without the funky 'chicklet' keys and 'spaced-out' appearance; and with additional indirect programming. Both RPN-mode and ALGEBRAIC-mode capable. it would appear to serve the needs of most anyone up to and including graduate-level biology-chemistry-geology-engineer types - it may soon be approved for use on the Professional Engineering Exam - as is the Hp-33. Do I like all of its functions? Well, no, I still think a dedicated Rectangular/Polar conversion would be more useful than having a 'mode-display shift', and key placement is taking a while to get accustomed to. Is the calculator immediately useful? Yes! I am used to the Reverse Polish Notation (RPN), having used it since 1975, but an Algebraic mode is available as well for those willing to put up with multiple parentheses. I *DO* wish the manual was available as a RPN-Only or ALG-Only, so all examples would be more useable. And I'd like it if the manual would go into more detail about some items (although on-line help on a variety of subjects is available at the HP site). The ability to write an EQUATION and have the calculator prompt for inputs (even in programming mode) is great, and the SOLVE function makes short work of various complex problems. The ARRAY functions and complex-number arithmetic capabilities are Outstanding, and are fully programmable - enter an array [ppp, qqq, rrr], another [sss, ttt, uuu] and instantly find Dot-product or other vector manipulations. Enter complex-number arrays [nnnieee, mmmiddd, llliccc] and calculate with them! The Unit Conversions are more than just basic Kg-Lb, C-F, Km-Mi, etcetera; there is a fairly complete library of basic physical and mathematical constants (which apparently may NOT be added to) and which may be easily entered in formulas or recalled for use. The Statistics functions are useful and complete, giving of: SX, SY, SXY, Sx^2, SY^2, and n (Where Sum = (S)). The four-level 'program-stack' makes it easy to get and use intermediate solutions (at least in RPN mode) without having to store and recall intermediate answers. Programming appears to be straight-forward, with memories A through Z available for programs, and indirect addressing to expand this functionality (I am still investigating this aspect). What it Does Not do: Well, it IS NOT a graphic calculator. But then, do you really NEED a graphics calculator for basic (or even advanced) everyday use? Maybe not. The size and weight of the HP-35 lends itself well to having it available almost everywhere. The zippered fully-protective case is well thought-out, and appears to be durable and functional. Personally, I find the key layout (functional grouping) and key construction to be far better than other competing calculators. The functions are internally consistent, in that Sin(nn) is (in RPN mode): nn Sin, and Y^X is always nn rr 'Y^X' not sometimes the function then the argument while other times the argument Then the function: the calculation methodology is always the same. I find the calculator to be an excellent bargain for the money. 'Wish-List': What I would *REALLY* like would be just a little Mini-USB in/out port so programs could be loaded without having to key everything in (and maybe Printed as well).Read full review

HP 33s Review

I bought the HP 33s because it is one of the few calculator you can use on the surveyors exam. It's a descent calculator. I've only ever really used texas instrument TI models and this one. This is the better of the two kinds if you're in the engineering or surveying field. You can program equations and programs on the calculator. I prefer inputing equations because it's more strait forward and easier to understand. I'm stuck on this calculator because it's the one I know best. I'm sure there are other better calculators out there but I do like this one.
