Scientific calculator

Mathematical Functions: • Basic Arithmetic: Addition, subtraction, multiplication, division • Fractions: Perform calculations involving fractions and mixed numbers (A b/c key) • Powers and Roots: Square (x²), cube, nth power (xʸ), square root (√), cube root (³√) • Exponents and Logs: Exponential (EXP), natural log (ln), and log base 10 (log) • Factorials & Combinations: n!, nPr, nCr • Reciprocal: 1/x function • Random Number Generation: RANDOM key Algebraic & Advanced Math: • G.C.F. (Greatest Common Factor) and L.C.M. (Least Common Multiple) functions • Integer Division & Modulus: INT÷, mod functions • Fraction Simplification: SIMP key simplifies fractions to lowest terms • Conversion between Fractions and Decimals: F↔E key • Parentheses: For multi-level expressions Trigonometric & Angular Functions: • Trig Functions: sin, cos, tan and their inverses (sin⁻¹, cos⁻¹, tan⁻¹) • Angle Modes: Degree (DEG), Radian (RAD), and Gradian (GRAD) – selectable with the DRG key • π (Pi) Constant: Built-in π key for precision calculations Statistical Functions: • One-variable statistics: Mean, standard deviation, sum, and sum of squares • Data Entry Mode: For entering and analyzing statistical data sets Memory Functions: • Memory Storage & Recall: STO, RCL, M+, M- • Multiple Memory Registers: For saving and retrieving interim results Convenience Functions: • Equation Mode (EQN): Solves simple algebraic equations • Constant Calculation: Repeats last operation with new input • Automatic Power Off: Saves battery life • Error Check & Clear: CA and DEL keys for correcting input errors
