“Natural Textbook Display”: It shows expressions (fractions, powers, roots, square-roots, exponents, integrals, etc.) on screen in the same format as printed in textbooks — making them easy to read and understand. Wide function support: Includes hundreds of mathematical functions: trigonometry, logarithms/antilogs, exponentials, powers & roots, factorial/permutations/combinations, hyperbolic functions, and more. Advanced math capabilities: It can perform more advanced operations — matrix and vector calculations; complex-number computations (real + imaginary); base-n (binary/octal/hex) calculations/conversions; equation solving (polynomial, simultaneous); integration & differentiation.
