Casio FX-82CW ClassWiz Scientific Calculator, Black

The Casio FX-82CW ClassWiz is a 12-digit scientific calculator designed for school-level mathematics and engineering coursework. It offers over 290 functions and features a high-resolution 63 x 192-pixel, 4-shade grayscale display. Using the Natural V.P.A.M. system, the calculator shows equations as they appear in a textbook, and the screen layout maintains legibility for long strings of operations.

The unit runs on a single AAA battery and includes an automatic power-off feature to conserve energy. Measuring 77 x 13.8 x 162 mm and weighing 100 g, it is compact enough for a school bag or desk. This model does not include a protective cover, so the screen and button interface remain exposed when not in use. Navigation is handled via an icon-based menu. The keyboard includes dedicated keys for negation and scientific notation, alongside nine memory registers for storing values. The calculator also supports automatic fraction simplification and conversions between trigonometric and logarithmic functions.

• 9 memory registers — for storing and recalling intermediate values.
• 24 levels of parentheses — for inputting complex nested formulas.
• Random integer generator — for statistical and probability tasks.
• Natural V.P.A.M. entry system — displays expressions and fractions in a textbook-style format.
• Angle conversion — for switching between degrees, radians, and grads.
• Exact decimal approximation switch — toggles between fractional results and decimal equivalents.
