Tokyo, February, 16, 2015 — Casio Computer Co., Ltd., announced today that it will release the ClassWiz fx-991AR X calculator. Equipped with a high-resolution LCD, the new model is the world’s first*1standard scientific calculator*2that displays Arabic script on the screen. It will be released in the Middle East and in Arabic-speaking African countries.

*2A scientific calculator without programming functions

Casio supports mathematics education through its diverse lineup of scientific calculators, including standard models capable of complex computations, programmable models equipped with programming functions, and graphic models that combine graphic input functions with programming functions.

The new ClassWiz fx-991AR X model features a high-resolution film-compensated super-twisted nematic (FSTN) display with 12,096 dots—approximately four times the 2,976 dots offered by the previous Casio model*3and is the first standard scientific calculator with an Arabic menu and guidance. The high-resolution display is easy to view numerical formulas and symbols. The ClassWiz fx-991AR X minimizes abbreviated menu items and guidance, making user instructions and information on screen easy to understand even for a beginner. This scientific calculator is also equipped with a spreadsheet function that is useful for entering recursive formulas and studying statistics, which has become increasingly important in recent years in educational settings. This means the ClassWiz fx-991AR X can be used for calculations found in the latest textbooks and for more complicated calculations than previous models.

The ClassWiz fx-991AR X includes a function that can display a graph on a smart device such as a smartphone or tablet computer. This enables numerical formulas inputted into the calculator to be converted to Quick Response (QR) Code. Users can display graphs on smart devices by reading the QR Code*6to access a dedicated website. This function can also be used to display the calculator’s user manual on a smart device.

*6QR Code is a registered trademark of DENSO WAVE INCORPORATED in Japan and in other countries.

By utilizing a high-resolution display, Casio has raised the level of the user interface for its calculators, allowing icons to be displayed more clearly and legibly on the menu screen. Furthermore, the ClassWiz fx-991AR X is capable of performing sophisticated calculations such as differential calculus, linear and vector operations, 4×4 matrix calculations, and 4-variable simultaneous equations. The new model comes with a two-way power system combining a battery and solar cell.

Along with the ClassWiz fx-991AR X, Casio plans to release three additional standard scientific calculator models equipped with the same high-resolution display.
