Get professional performance from the ultimate RPN scientific programmable calculator. Switch between RPN1 and algebraic entry-system logic at any time. The HP 35s features a two-line display, and the powerful HP Solve2 application.

The HP 35s uses either Reverse Polish Notation (RPN) or Infix notation as input.

Other features of the HP 35s include[1]:

• Two-line alphanumeric LCD display
• 26 memory registers
• Scientific and statistical functions
• Operation in decimal, binary, octal, hexadecimal
• Equation solver (a feature first seen on the HP-34C)
• Numerical integration (also first seen on the HP-34C)
• Support for input and display of fractions
• Complex number and vector calculations
• Unit conversions and table of physical constants
• Approximately 30 kilobytes of memory for programs and/or data

Although the HP 35s has far more functions, processing power, and memory than the original HP-35 which it commemorates, Hewlett-Packard has attempted to give the HP 35s the look of the original HP-35 and other HP calculators of that era. It also features the sloped-front keys for which HP calculators (although not the original HP-35) are well known.

THE HP15C IS SOLD OUT

Probably we will not have any more units. Sorry!

The intelligent design of the HP 15c Scientific Calculator facilitates portability and convenience, ensuring that your 15c is always handy, and incorporates RPN mode, simplifying data entry. The 15c provides what engineers and scientists rely upon: complex number calculations, matrix operations, numerical integration and root solving. For the collector, the Limited Edition 15c presents an opportunity to own a classic HP calculator that has not been available for over 20 years.

Math and science students will appreciate the logical, accurate, and dependable HP SmartCalc 300s Scientific Calculator. Besides showing the result, the impressive Textbook Format Display (TFD) shows the math expression onscreen, just like it would appear on paper. Use the intuitive navigation pad to move around within an expression to change it and watch the result. With 249 built-in functions, students can solve an abundance of math problems from basic to complex.
