Product details
fx-991EX is a high-performance, non-programmable scientific calculator from the ClassWiz series, ideal for high school, college, and advanced mathematics. It features a high-resolution LCD dot-matrix display (192 × 63 pixels) that shows up to 10 + 2 digits (10-digit mantissa + 2-digit exponent) and supports Natural Textbook Display, allowing fractions, roots, integrals, matrices, and other expressions to appear exactly as they do in textbooks.
Key Features:
• Spreadsheet calculations → Handle data lists, basic formulas, and up to 5 columns × 45 rows for real-world data analysis.
• 4×4 matrix calculations → Including addition, multiplication, determinants, inverses, and solving systems of equations.
• Vector calculations → Support for 2D and 3D vectors, with operations like dot/cross products.
• Integration and differential calculations → Numeric definite integrals, derivatives, and advanced Riemann functions.
• Advanced statistics and distributions → Normal, binomial, Poisson, regression, and more, with list-based data entry.
• Equation solving → Simultaneous equations (up to 4 unknowns), polynomials (up to degree 4), and inequalities.
• Additional tools → Ratio calculations (A:B=X:D), metric conversions, 47 scientific constants, 40 unit conversions, prime factorization, complex numbers, base-n (binary/octal/hex), and QR code generation for graphing/visualization on smartphones
