Description
The Smartest ClassWiz Ever Made.
Casio's most advanced non-programmable scientific calculator — 550+ functions, natural textbook display, and QR code connectivity for the modern math learner.
Key Highlights
📐 550+ Mathematical Functions — The most comprehensive function set in Casio's ClassWiz lineup
📱 QR Code Function — Generate QR codes to visualize graphs and calculations on your smartphone
📺 High-Resolution LCD Display — Natural textbook display shows equations exactly as written in books
➗ Natural Textbook Input — Enter fractions, roots, and equations in natural mathematical notation
🔢 Spreadsheet Function — Built-in 5-row spreadsheet for data analysis and statistical calculations
📊 Advanced Statistics — Comprehensive statistical functions including regression and distributions
🔋 Solar + Battery Power — Dual power for reliable operation in any lighting condition
🏫 Exam Approved — Approved for use in major international and local examinations
The Casio FX-991CW ClassWiz Scientific Calculator is the flagship model of Casio's renowned ClassWiz series — the most advanced non-programmable scientific calculator Casio has ever produced, and the definitive tool for students, engineers, and mathematicians who demand the highest level of calculation capability in a handheld device.
At the heart of the FX-991CW is its extraordinary 550+ function library — covering every mathematical domain from basic arithmetic through advanced calculus, complex numbers, matrix operations, vector calculations, equation solving, integration, differentiation, and statistical analysis. Whatever mathematical challenge your curriculum or profession presents, the FX-991CW has the dedicated function for it.
The QR Code connectivity feature is what truly sets the FX-991CW apart from every previous ClassWiz model. By generating a QR code directly on the calculator's display, you can instantly visualize your calculations — graphs, statistical distributions, geometric figures — on your smartphone using Casio's free app. This bridges the gap between handheld calculation and digital mathematical visualization in a way no previous calculator has achieved.
The high-resolution Natural Textbook Display shows mathematical expressions exactly as they appear in textbooks and academic papers — fractions display as stacked numerator/denominator, roots show with the radical symbol, integrals appear with their proper notation. This natural input and display format dramatically reduces entry errors and makes reviewing calculations intuitive and natural.
The built-in spreadsheet function handles up to 5 rows of data with formula support — enabling data analysis, statistical calculations, and systematic numerical computations that previously required a computer spreadsheet application. For physics, chemistry, statistics, and engineering students, this is a significant practical capability.
Advanced statistical functions include data classification, frequency distribution, regression analysis (linear and multiple), and statistical distribution calculations — covering everything required for A-level, university statistics, and professional data analysis work.
The dual solar and battery power system keeps the calculator running reliably through exams, fieldwork, and extended study sessions regardless of ambient lighting conditions.
For SEE, NEB, +2, Bachelor's, engineering, and professional examination students in Nepal — as well as engineers, scientists, and mathematicians requiring a powerful handheld calculation tool — the Casio FX-991CW ClassWiz is the unambiguous top choice.
