Rated 4 out of 5 by from A lot of calculator for the price Three things first: 1. The HP-300s+ calculator does not have RPN logic. If you'd rather have RPN capability, go for a different model like the HP-35s. 2. The HP-300s+ does not have the excellent, double-molded hinged keys seen in classic HP calculators. The HP-300s+ keys lack tactile feedback and are no better than are those seen on all but the cheapest of calculators. 3. The calculator is not programmable. A prospective buyer should read the online manual before purchasing to make sure that necessary functions are included as gaps can't be covered by programming. And the rest: The HP-300s+ offers a lot of functionality for its price. Almost every scientific function needed by a high school student is there, and I'd guess that most college students with majors outside the hard sciences or business would be satisfied as well. It's a nice addition to a student's backpack and its low price means not too many tears if it were lost or stolen. The four line LCD display is easily readable under classroom and office lighting. That same lighting also powers the HP-300s+ while a small battery provides back-up capability. The displayed digits are not very large, but you'll get more of them compared with other models. There has been a considerable effort made by the designers to support the graphical representation of radicands, subscripts, superscripts, parentheses, et cetera as they would appear in a formula from a textbook. Formulas can also be edited without much difficulty using the cursor keys. Having a formula represented in a natural manner is, to me, a requirement for any calculator with algebraic entry. Having to rely on the correctness of hidden pending operations and parentheses placement is the bane of old style algebraic calculators and that's why I don't use such models. So while the HP-300s+ lacks RPN, at least it shields a user from hidden hazards. The HP-300s+ has an "alpha" shift key, but only nine letters are available. Each can be used as a memory label for storing a value. The "On" key is slightly recessed to help prevent accidental activation. The "Off" key requires a shift as it should. The shifted operation legends are printed in blue on black and are not as easily seen as the higher contrast blue on white legends on the HP-10s+. The HP-300s+ has four small rubber feet on its back and another set of four on the back of its separate case; a nice feature when compared to the near useless feet on the HP-10s+ which are just hard plastic without any grip. The calculator supports twenty pairs of conversion functions. These are indexed by a two digit code on a cheat sheet attached to the inside of the separate hard back. The calculator will display the conversion function, but only after the function is selected by its index. One would think that the cheat sheet would be better if it were attached to either the back of the hard case or the back of the calculator. In summary, the HP-300s+ is a good value. Compared to the slightly less expensive HP-10s+, it has a few more functions and provides a much better display of a formula. It's worth your consideration; if for some reason you buy one and don't like it, you could always gift it to a deserving student.

Rated 1 out of 5 by from I hate it! I'd send it back if the postage wouldn't exceed the cost of the calculator. The display is very dim and hard to see. Also, it gives answers in fractions. Although there is a key to switch to decimal, I don't see any way to specify decimal as the default answer format, nor does there appear to be one in the users manual. The answer to 3/2 displaying as 3/2 isn't helpful, and I don't want to have to press another key to get 1.5. If someone knows how to specify decimal as the default answer format, please tell me!
