Be warned, if you are looking for a "normal" calculator and you have no idea how an HP calculator works or what Reverse Polish Notation (RPN) is, then you may need a couple of hours to get used to the new way of thinking when operating this calculator. However, many who tried RPN prefer how this system makes it easier to organize a calculation, store intermediate results, and to make programs. Google "RPN tutorial" and get started, don't complain that this isn't a normal calculator.

And no alternative is forthcoming) * 300+ mathematical functions and operations (reach all of them in max 4 taps) * Programmable * Draw, integrate, differentiate and solve your programs * Complex numbers * Matrices * Calculate with and combine 120+ units and convert between them * Binary, Octal and Hexadecimal number representation * High precision (16+ digits), wide range numbers (10¹⁰⁰⁰⁰⁰⁰⁰⁰) * Scientific constants with units * Statistics with curve fitting and graphing * Financial calculations * Flick between multiple stacks * Export and import results, memory, programs and more via clipboard * Press and hold any button for help
