This is a great affordable calculator for 6th graders who are entering into Algebra. I'm not going to give a review of all the features, and this calculator has man, but it does have the features my pre/algebra 6th grader needs. It will do fractions including mixed number fractions. It also has an reciprocal (1/x) feature which is handy. Also, it has a niffty simple equation solver (2x+5=15 for example) which is simple to use. Ratios can be done as fractions so that is already covered. So, it pretty much covers fractions (simple and mixed), ratios and it has an equation solver (that allows you to put X on one side or both sides of the equation and you can put fractions in the equation too). So, it pretty much covers 6th grade math anyway. This calculator does not graph though. So, for math classes that do a lot of graphing or graph analysis you will need a graphing calculator.

I am used to HP graphing calculators but sometimes you need something else. This is a replacement for another Casio and just like the last one looks like a 10. Plenty of functions and modes to go around ,sturdy protective case. A calculator you can throw into your toolbox and know it will be up and ready when you need it- if not….you can easily afford another one.

Una calcolatrice ottima. Aspettarsi di meno da Casio sarebbe poco plausibile.Veloce e pratica, forse varrebbe la pena il modello con monitor grafico vista la differenza di spesa.Consiglio decisamente

Compré esta calculadora para mi hija y está contenta. Ella tuvo la Casio FX-991ES Plus la primera edición y le duró muchos años, lamentablemente dejó de funcionar y por eso me decidí a probar con el mismo modelo pero la segunda edición. Es una calculadora muy completa, me gusta porque es solar y no es programable, lo que la hace permisible para utilizar en los exámenes.Buena relación calidad-precio.La recomiendo.
