Digital camera reviews of Casio FX-115MS Plus Scientific Calculator
Digital camera Review: Solving quadratic and cubic equations
Summary: 2 Stars
Entering the EQN Mode and pressing the "right arrow" key, does not display the quadratic and cubic equation screen and as a result I can not solve these types of equations, which I need frequently.
Other than this it looks yet ok to me.
Thanks.

Digital camera Review: Sweet review
Summary: 5 Stars
It came in the condition described, came by the estimated shipping date. I would definitely buy from this company again. Very reliable.Digital camera Review: Tabula rasa
Summary: 3 Stars
This inexpensive scientific calculator (Fx-115MS Plus) has many desirable features:
o two line display with clean input/output functional separation (unlike the Sharp 506W)
o expression recall and editing
o highly visible recessed display (unlike the Sharp 506W)
o roomy and well-organized key-layout
o great tactile feedback
o hex/oct/bin bitwise operations
I love the brushed stainless, low-gloss, look and the calc body is narrow enough to permit one hand operations.
It also comes with a nifty equation solver, which unfortunately is not well documented. At first I thought the example given (B=AC-(1/2)DC^2) needed be rewritten (AC-(1/2)DC^2-B, implicit [=0]). However, I was using the wrong {alpha}{=} key sequence to enter "=". What must be used is {alpha}{calc}--the {calc} key has an alpha tertiary label "=". The solver is also slow. A Time Value Money interest solution required 55 seconds, whereas on the HP33s the same evaluation was completed in 7 seconds. What impresses over other units in this price range is that prompting for variable input supports a large subset of the expression grammar (no references to other variables are permitted).
Expression history and editing have a few quirks. No flashing cursor to show initial insertion point. An initial {<} positions cursor at the far right! The default edit mode is "overwrite" not "insert". Insert is the default for most text editors--why not work with user assumptions?
However, as one reviewer previously mentioned, the major shortcomig of this unit is the clearing of equation history on power down. Since there is no equation memory (as on the HP33s), the least Casio could have done is NOT make equation history clearing automatic. Power it down or leave it idle for more than six minutes and those equations you've labored over are gone!
Sleek, svelte, and sometimes elegant but an empty slate.
Digital camera Review: Terrific School Calculator
Summary: 5 Stars
I bought this calculator from Staples for $14.99 on August 11, 2001. Then, I lost it about a week ago lol. After having it for two years, I'm VERY pleased with it. The look of it is a lot better than the Texas Instruments and all the buttons are in the place that you would put them if you were designing it. The two-line display works great and you can recall up to 8 problems on the calculator. The only drawback is the battery dies out after awhile, but then the solar panel comes in handy. Overall, this calculator is great. Any Casio product I have liked. Since I found this on Amazon I think I'm going to purchase another one as a replacement. I recommend it.Digital camera Review: The End All Be All of Easy to Use Scientific Calculators

What can I say? I love this calculator. Not only is it easy to use, but its the perfect size, weight, and shape to fit in your hand. The thinness is wonderful and the click on case is great for storing notecards in between it and the calculator. Its two way power which is great. Function button placement is logical. I've been using this calculator for 3 years now through all my chemistry and physics courses and can honestly say I would never use another.
PS you can definitely say that I have converted from the TIs!
