## Overview

The Casio FX-991ES Plus-2 is a scientific calculator featuring a natural textbook display that visually mirrors mathematical expressions for enhanced understanding. Equipped with a fast equation solver and comprehensive fraction and ratio functions, it supports learners from middle school algebra to university-level math. Lightweight and powered by a rechargeable lithium-ion battery, it combines portability with reliability, making it a top choice for professionals and students aiming for precision and efficiency.

## Description

The natural display (natur-v.p.a.m.) It shows mathematical expressions such as roots and fractions that appear in your textbook, and this increases understanding as the results are easier to understand.

Review: Great for 6th grade algebra - 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.
Review: Works as advertised - Daughter has been using this for a year in university level math courses.
