The Casio FX‑82ES PLUS‑2 is a non‑programmable scientific calculator ideal for students and professionals, offering 252 built‑in functions. It uses a Natural Textbook Display, which shows mathematical expressions (fractions, exponents, roots, etc.) exactly as they appear in textbooks.

Powered by a single AAA (R03) battery, it’s easy to maintain and energy efficient. The display supports 10 + 2 digits — that means 10 digits for the mantissa plus 2 digits for the exponent.

Key features include prime factorization, fraction calculations, combination and permutation, and coordinate transformation capabilities. It also supports statistical functions, such as regression analysis and standard deviation, through a list-based STAT data editor, with up to 9 variable.

One especially useful feature is the table function, which lets users register a function and automatically generate a numerical table based on it. For input correction, it has a multi-replay function, so you can quickly recall and edit previously entered expressions.

Build-quality is strong: it has wear-resistant key printing, a drop-resistant body, and a rounded ergonomic design that fits comfortably in the hand. The calculator comes with a slide-on hard case for protection when carrying it.

Its dimensions are 161.5 × 77 × 13.8 mm, and it weighs about 105 g, making it portable yet solid.

Finally, the FX‑82ES PLUS‑2 supports an authenticity check: a QR code and hologram system helps verify that the calculator is genuine.
