A Scientific 300 functions calculator that is Solar powered with a battery back up.
It has Trigonometric CALC key and Time Calculations.
It has Quadratic equations plus differentiate and integrate.
It is ideal for Engineers or Engineering studentsetc as it has the Symbols.
The FX115MS is a great calculator and is a step up from the casio FX-83. It has all the features of the typical scientific calculator and all the keys are in similar places as the FX-83 and the other Casio models. However, what makes the FX115MS stands out from the rest is that it can solve quadratic equations plus differentiate and integrate. If you have had problems integrating or you want to check your answers then this calculator will find the solutions for you. It is also a general purpose scientific calculator but leans towards the engineering side. It has approximately 300 built-in functions but has no graphing capabilities. It is a two line display model and some deceptively sophisticated programmability. The top line is for your input, the bottom line is where the calculator gives its answers. Keys can be used for various operations depending on the state of the calculator. You set up the mode you need on the FX115MS by using SHIFT and ALPHA keys or by putting the calculator into mode.You can tell the mode of the calculator by the indicators above the first line of the display.See all Product Description

1) The replay keys aren't much use with this type of display for long calculations. They are much more useful with the display of the FX-570.
2) (Regarding complex numbers) there's more key pressing to switch between real and imaginary components (or modulus and argument). The FX-570 allows both to be displayed simultaneously on 2 lines.
3) The reciprocal key has 2 modes of operation. I use this a lot when working out parallel resistances. It works as expected from within a calculation, but after pressing = it takes on a temporary nature. If you do this and then use the displayed answer in a subsequent calculation, it'll use 1/R in the calculation; not the displayed value R. This also applies to storing such values in memory. The FX-570 doesn't do this.
4) (Again regarding complex numbers) storing these in a memory saves time over having to enter the number in full each time. There is also an answer memory which stores the result of the last calculation. If you start a new calculation using a value stored in one of the memories, you must press = to update the answer memory, otherwise it will use the value in answer memory in the calculation rather than the value you have recalled from one of the other memories. Very annoying.
Considering this and the FX-570 are both made by the same company, I'm amazed at the difference in operation. I can get along with the latter but this one is hard work.Read more ›
My biggest complaint about this calculator is that its screen display is too primitive and inflexible. Both the Casio fx-85GT and fx-991ES have very good displays that let you easily see fractions and functions the way you would expect to see them. While the Casio fx-115MS can only display two lines of numbers, one line for the input and one for the output. This means, for the Casio fx-115MS, those fractions would be displayed on a single line and be more difficult to input, read and edit. Other problems include not having a table function (that I can find anyway) and the way it displays output fractions can be confusing to less experienced users.
On the upside, it has a better physical feel than the newer Casio calculators I mentioned above. The two I own have been reliable. I've never had problems with power and if I'm lucky, I'll never have to change its internal battery. I'll probably still own them 20 years from now, unless I get rid of them to clear space. As scientific calculators go, it's got most of the essential functions and memory features.
To sum up, I no longer use this calculator for any serous maths work as the newer calculators mentioned above perform much better. I would recommend this only for the basics of maths, GCSE and early A-Level mathematics because of its poor ergonomics and lack of a table function. This calculator would be a handicap during the later stages of an A-Level mathematics course. My recommendation would be to buy a newer model of calculator with more modern features unless exam regulations force you to use this.
The only down-side of the fx115 is the ergonomics of the design. I find it a pain that you have to press 'Shift' to get Pi, which is is so commonly used in engineering that you want it available in one keystroke. Also shifting modes (between number bases, or complex/real or degrees/radians) is a multi-keystroke operation, which it should not be. Overall the fx115 deserves high marks.
