The FX991 ES PLUS has many functions that can be use to solve many problems. Our users say they love the fact that the scientific calculator use two types of power, one solar and the other battery so is ECO friendly and you are safe to take it into an exam without it failing not to work. Others opinions of the product is that they think that it is one to the best calculator that you can buy. One of the advantages that we are told about is that the result that you get you able to use the same figure in the next part of the sum, without having to round up numbers or to re-type up the whole digits which can lead to errors. Other great functions that we are told about was that you are able to use the calucator to work back wards, such as in algebraic equations. This can make life so much easier or so our users tell us.

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.
