Casio FX-115ESPLSB Advanced Scientific Calculator

Handle classroom and technical calculations in familiar mathematical notation with the Casio FX-115ESPLSB advanced scientific calculator. Its Natural Textbook Display uses a dot-matrix LCD to show fractions, roots, powers and other expressions in a textbook-style format. The 10 + 2 digit display supports display-format settings for fixed, scientific and normal notation, plus recurring decimal results and engineering notation. The 252-function set covers basic arithmetic, fraction calculations, degree-minute-second calculations, factorials, powers, roots, trigonometric and inverse trigonometric functions, logarithms, coordinate conversion, combinations and permutations. It also provides prime factorization, GCD and LCM, random-number generation, summation, product calculations, rounding, replay and multi-replay functions. Nine variables, independent memory, answer memory and previous-answer memory help retain values while working through multi-step problems. Casio FX-115ESPLSB-WA-IT also supports complex-number, matrix and vector calculations, differential and integration calculations, equation solving, inequalities and expression equality checks. CALC and SOLVE functions assist with evaluating expressions and finding solutions, while list-based statistical data entry supports basic statistics and distribution calculations. Forty stored scientific constants and metric conversion functions provide reference values for physics- and chemistry-related work. Auto power off and an approximate three-year AAA battery life support regular classroom, examination-preparation and field-study use.
