The Natural Textbook Display is one of the most useful features of the ES series. Natural Display allows fractions, irrational numbers and other expressions to appear in a format that resembles the way mathematical expressions are normally written on paper. Casio documentation describes Natural Display as showing expressions in a paper-like format.

For students, this can make calculations easier to understand. Instead of interpreting every expression from a simple linear display, users can view mathematical expressions in a more familiar format.

For example, fractions and square-root expressions can be easier to read when they are displayed naturally. This is useful while checking homework, practising textbook exercises or solving scientific problems.

The Natural Textbook Display can also help new scientific-calculator users become more comfortable with advanced mathematical calculations.

Dual Power for Convenient Use

The Casio FX-991ES Calculator is designed around convenient power operation. The specified product configuration uses solar power with battery backup, allowing the calculator to be used in suitable lighting conditions while maintaining battery support when required.

Solar-powered scientific calculators are convenient for students because they do not always need to depend entirely on a replaceable battery during normal use.

The combination of solar and battery power is especially practical for regular academic use. Students can keep the calculator ready for homework, classroom practice, coaching sessions and other calculation-related activities.
