CASIO's original Natural Expression Input Display and Natural Expression Output Display make it possible to display fractions, exponents, logarithms, powers, and square roots just as they are written in the textbook. The result is enhanced student comprehension and improved math class efficiency.The FX-991ES PLUS has a matrix display and solving equations has never been easier with new functions. Another is random Integers where you specify the range of random integers you want to generate and the FX991ESPLUS will display them. The number of memories has also been increase from 7 to 9. The FX991ESPLUS has many functions that can be used to solve many problems. Our users say they love the fact that the FX991ESPLUS use two types of power, one solar and the other battery so is Economy friendly and you are safe to take it into an exam without it failing not to work. One of the advantages that we are told about is that the result that you get you able to use in the next part of the sum without having to round up numbers or to re-type which can lead to errors. You are able to use the calucator to work backwards, such as in algebraic equations. This can make life so much easier. The high technical specifications make this the most powereful Scientific at this price point. You can use this calculator from School to University and on into work.
