This is one of the best Casio Scientific Calculator with very affordable price. This calculator is now available in Bangladesh also @ http://www.bdshop.com/casio-scientific-calculator-fx-991es-plus
417 functions very light weight and very easy to fall from hand.

All great. I bought a calculator for high school graduation, 14 days after buying banned calculator funkcema ... not negative calculators.

Large clear buttons. Readable display. Generator and whole random numbers. Natural notation, eg. 2A ^ 2 is properly evaluated as 2 ^ * A second Frequency of values ??in the statistics. SUM function x (i-n). If it makes sense, returning results with absolute precision - in fractions of a odmocninách. At this price level, you will not find better. Not permitted in GCE (this of course is not her fault) The statistics feature is missing median, mode. The variation width must be manually calculate MAXX Minx. Has (unfortunately) advanced statistical functions such as chi-square, u-test, t-test, etc.

Probably the best non-programmable calculator on the market today. Intuitive controls many functions (for high school students and for most undergraduate courses, if you are not on Matfyz, totally satisfactory), clear display, dual power. Perhaps just might be able to count on the nuts bigger than 3x3. It suits me very natural logarithm function button on an optional basis. I found two drawbacks. One silver color goes down over time, so the year used a calculator does not look very nice. The second is an error (if present at all Casio know this series - but such. Outstanding programmable Casio FX 5800P it does) in priorities: the expression 5/5 (5) evaluate the calculator as 0.2, although it should come out 5 (multiplication has precedence over division . The correct result should be corrected before the brackets explicitly write times, which in more complex expressions ignorant can cause unpleasant complications.
intuitive control of many functions can also nuts (but max 3x3) arranged display expressions can be written to and displayed in the same format as on paper silver paint was scraped mistake in priorities (before the bracket is the right priorities nuytno write times explicitly)

Large display and a much better overview in complex calculations to the older models of Casio. When switching to another mode erases the results of calculation on the display. When storing the result in memory also deletes the calculation of the display, which in older Casio did not happen.

Price large number of functions Without complex matrix of numbers is impossible to impose a feature

Contentment, a decent price calculator with many features for undergraduate and high-school students an excellent aid ... It takes a while until you add it to your taste (especially relating to more complex calculations), just give directions about 30 minutes and operate all what you will offer a calculator.
Design calculates definite integrals simple instructions Synoptic reckoning fashion through a complex calculation of derivation They could mend Newer type (if it is not), which envisages a double integral vicarious
