Review of CASIO FX115-MS SCIENTIFIC CALCULATOR WITH 300 BUILT-IN FUNCTIONS

Average Reviews:

(More customer reviews)Have used Casio scientific calculators throughout my life. I've had my 115MS for some three years now. I use it for electronics design and I've been constantly amazed at how every special function I ever need is there. Binary/hex/decimal conversions, engineering conversions including metric prefixes (kilo, micro, nano, pico etc. which I find simply indispensable), complex numbers, etc. The CALC function is particularly useful when I want to see how different values will alter the answer to a formula/equation.

One thing that peeves me though is that it takes three keystrokes to store a value in memory (variables). That's cumbersome.

Overall this inexpensive calculator gets a three thumbs up from me. If Casio makes an exact model with added programmability, I think it just might be the perfect calculator for me.

Review of Casio FX-55X Solar Scientific Calculator

Average Reviews:

(More customer reviews)This is a pretty good calculator with a few functions in them. This calculator is very easy and simple for anyone to use because you won't getconfuse over the few functions it has. You don't have to search around forthe many functions you are looking for.It is good for people who doesn'tlike to have to many function like using the 2nd key for other functions.It has a nice fraction key for people to see the fraction the way itssuppose to be. There are also many functions on this calculator that itdoesn't have that is really important for math.

Review of Sharp EL-531VB Calculator

Average Reviews:

(More customer reviews)I have been using a version of this Sharp calculator from early high school all the way up thru a Master's degree in Electrical Engineering and now as a professional - it rocks! For science/engineering students, there is none better. It is simple and will do everything you need (almost - see below). Forget about those cumbersome, expensive graphing calculators. Save some money and buy one of these bad boys instead. Graphing calculators are a waste of time - learn how to do it on paper. This calculator deserves 5 stars, but I can only give it 4 because they took away the conversion functions for hexadecimal, octal, and binary numbers - essential for computer science & electrical engineering students. What the heck! Where can I still buy the EL-506? Mine finally broke...

Review of CASIO - FX-115MS+ Scientific Calculator

Average Reviews:

(More customer reviews)For many years, I used a Casio Scientific that had no battery. It meant that I had to be sure that there was some light (not much at that) in order to use it. It was stolen and I've been trying to replace it. This models description didn't indicate that it had or needed a battery so I bought it. It has a battery and indications from the (enclosed) directions seem to indicate that is required and must be replaced when it goes dead. there is little more irritating to me than having to find a special battery for something for many reasons. That, and the awkward "case" are the only faults I find with it but they are enough so that I find myself willing to give it away soon (before the battery ages or the case gets lost). I should point out that the calculator depicted FX1115MSPLUS doesen't have the BIG round button mine has and mine doesn't call itself ...PLUS. the one in the picture might be the one I ordered but didn't get. ??? I sure hope someone reads this... .

Review of Hewlett Packard HP6S SLR Solar Scientific Calculator

Average Reviews:

(More customer reviews)This calculator could be one of the very best scientifics sold by ... but it is not. In fact, it is not best for the price, even.
The best scietific is the Hewlett Packard 32Sii but it costs near to 60$ U.S. which means they are not a `give to the kid to take to school' item. Being the `nerdly grand unki' I get to help all the school-agers with their math homework. I agree with the math teacher, here, that this is an `O.K.' calculator but given the present shipping-cost addition to this calculator I suggest one would be better off buying the algebraic entry Hewett Packard 30S or [even] the Texas Instruments 34 II.
Somehow the `RPN' or postfix entry system is thought of a `hard to learn'. The kids here all use it, there are several Java based RPN calculators on the WWW but this calculator doesn't have RPN. If it did I would buy several. Without RPN I cannot even highly recommend this well built fairly easy to use [but no kid likes the siff rubber keys, calculator.
