Casio FX-991CW-W-DT ClassWiz Scientific Calculator

The Casio FX-991CW-W-DT scientific calculator has been designed as part of the advanced ClassWiz CW series to support intuitive and effective mathematics learning. A high-resolution, four-level display has been implemented to clearly distinguish the current input position using darker contrast, improving readability and reducing input errors. An updated key layout and cursor-based operation have been introduced to follow a natural user flow, making navigation simple and accessible for students.

Learning efficiency has been enhanced through calculator applications that can be selected directly from the main screen depending on the type of calculation required. Online visualization has been enabled through QR code generation, allowing equations and data to be viewed as graphs on smartphones or tablets. Additional educational tools such as Math Box functions, table creation, statistical analysis, and variable storage have been included to support classroom learning and exam preparation.
