**Features Overview**

*High Resolution Display*

The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols.

*“Resolution 4x”*

- New Icon Display
- Innovative input method
- List Display

The new ClassWiz makes it possible to display on the screen twice the number of characters in normal size and six times the number in small size compared with previous models.

*High-resolution LCD drives further evolution!*

Higher resolution increases the amount of information that can be displayed and improves usability. In addition, ClassWiz is equipped with a basic spreadsheet function for creating spreadsheets with up to 5 columns and 45 rows (maximum of 170 data items).

ClassWiz technology has the power to change mathematics classroom

*Easy to Use*

Superb usability that takes full advantage of the improved display capabilities makes the interface easy to use in classrooms

**Intuitive Icon Display**

The use of icons on the menu screen improves viewability.

Selection of the desired function is quick and easy.**Unabbreviated English Display**

Nearly all English words are displayed on the screen in unabbreviated form.

*Messages are spelled out (not abbreviated)**Interactive format**

Interactive menu display realizes more intuitive operation.**Natural Textbook Display**

Input and display fractions, powers, logarithms, roots, and other mathematical formulas and symbols just as they appear in textbooks.

*Newly designed body for the best use of calculation*

Featuring intelligent design and an elegant texture

**Special surface processing**

A special surface process applied to the body results in an elegant texture and design.- Metallic keys (fx-991EX/570EX only)

The stylish look and feel of metal imparts a sense of luxury. **Key functions arranged by color**
