I have coached over 200 students in the last 8 years and this and the 991 are the two machines I recommend. Your typical solar powered calculator doesn't need a lot of energy to power it, a simple math chip. Love this for the SAT and ACT. The source doesn't matter for converting it into energy. I use calculators in my study that gets almost no natural light, and I've never had any die on me. . : pre-owned See and discover other items from category Pocket Calculators.

While this is not a CAS (Computer Algebraic System) calculator, it is very capable of solving simultaneous equations, working with complex numbers, and handling matrix and vector math. The calculator doesn't have RPN (Reverse Polish Notation), so if that is something that is important to you, condsider buying an HP instead. It is much smaller than I expected and the key layout is something that takes some getting used to. : Need advice? Very good calculator for the average student. you think, if it knew, it would not charge? Equations can be entered just like you would in a textbook, including integrals, derivatives, summations, proper and improper fractions, and more. has its own contextual features which are found in a menu displayed with the options button (OPTN). : commando casio gadgetian Explain Like I'm Five is the best forum and archive on the internet for layperson-friendly explanations. A combination of a rechargable battery built into the calculator and exposure to any light including artificial light is sufficient to power it. From: 1- 10? : . : . Every answer appears as a fraction, instead of a decimal. : Does calc, algebra, math - all very well. A TI-84 is a great calculator for graphing, BUT, you aren't graphing on the SAT exam. j.b.goods. Each mode (matrix, vector, statistics, etc.) I also recommend the CASIO fx- 991ES PLUS. For everyone else, I highly recommend this calculator for it's ease of use and sheer functionality.

The keypad and LCD probably draw more power than the rest of the system. :-). | Intuitive interface, crisp display, and solar powered too! The non- PLUS version of this calculator had beautiful buttons that aren't as loose as these, and allow your fingers to slide between keys much more easily. It has added functions that I've heard were removed from the US version so that the calculator would be allowed for certain curriculum / exams. If you've used the FX-300 / FX-115 ES or ES+ models before, you should feel right at home. While yes, solar panels designed for indoor use will obviously be designed to take advantage of the visible spectrum, the amount of energy you'll capture depends on the light source. Compared to the FX-115ES that I had before, the FX-991EX is several times faster, so they have upgraded the processor on this one, yet it is still able to run off solar power when needed. Light is light. 115es . | . The Classwiz FX-991EX is no exception. It arrived early. Calculators require very little energy to work so very little light is needed to make them work and it doesn't have to be sunlight any light will do. The visible spectrum is between 400-700nm. : : Scientific calculator with 696 functions and a high-resolution display. Don't Panic! Because of the solving equations functions under MODE, this is the best calculator for the SAT exam. I've owned quite a few different calculators over the years and have found that the Casio models in particular are very easy to use. . . Also of note to those considering this model: Something went wrong. Now the Sun is a lot brighter than most lamps, but a solar powered calculator doesn't use anywhere near that much energy. The COMPLEX numbers function is also extremely helpful. | : Artificial lights, such as florescent lights and incandescent bulbs, mimic the sun's spectrum. pre-owned According to the Casio International website, the FX-991EX has 552 functions and the Casio Europe website shows the FX-991DEX version as having 696 functions. Different lights give out different amounts of light under different parts of the spectrum, and silicon solar cells can only utilize light from, depending on exact construction, some wavelength range between 400-1200 nm. Overall, this calculator has good design and software, and is a very good buy. There is a German version known as the FX-991DEX that is available from Europe. pre-owned : The most used functions are the most accessible with a single button press, followed by slightly lesser used functions using the SHIFT key.
