Introduced at US$395, the HP-35 was available from 1972 to 1975. Like some of HP's desktop calculators it used RPN.
The HP-35, introduced on February 1, 1972, was Hewlett-Packard's first pocket calculator and the world's first handheld scientific calculator.

HP became closely identified with RPN calculators from then on, and even today some of their high-end calculators (particularly the long-lived HP-12C financial calculator and the HP-48 series of graphing calculators) still offer RPN as their default input mode due to having garnered a very large following. The HP-9100 series was built entirely from discrete transistor logic with no integrated circuits, and was one of the first uses of the CORDIC algorithm for trigonometric computation in a personal computing device, as well as the first calculator based on reverse Polish notation (RPN) entry. The first scientific calculator that included all of the basic ideas above was the programmable Hewlett-Packard HP-9100A, released in 1968, though the Wang LOCI-2 and the Mathatronics Mathatron had some features later identified with scientific calculator designs. by providing a method to enter an entire problem in as it is written on the page using simple formatting tools. They are very often required for math classes from the junior high school level through college, and are generally either permitted or required on many standardized tests covering math and science subjects as a result, many are sold into educational markets to cover this demand, and some high-end models include features making it easier to translate a problem on a textbook page into calculator input, e.g. They are also used for calculations of very large or very small numbers, as in some aspects of astronomy, physics, and chemistry. Scientific calculators are used widely in situations that require quick access to certain mathematical functions, especially those that were once looked up in mathematical tables, such as trigonometric functions or logarithms. A few have multi-line displays, with some models from Hewlett-Packard, Texas Instruments (both US manufacturers), Casio, Sharp, and Canon (all three Japanese makers) using dot matrix displays similar to those found on graphing calculators. While most scientific calculators have traditionally used a single-line display similar to traditional pocket calculators, many of them have more digits (10 to 12), sometimes with extra digits for the floating-point exponent. letters that can be used for spelling words or including variables into an equation.

When scientific calculators were originally marketed they normally had only four of five capabilities (addition, subtraction, multiplication, division and square root). In some areas of study scientific calculators have been replaced by graphing calculators and financial calculators which have the capabilities of a scientific calculator along with the capability to graph input data.

They have completely replaced slide rules and are used in both educational and professional settings. Casio fx-77, a solar-powered digital calculator from the 1980s using a single-line LCDĪ scientific calculator is an electronic calculator, either desktop or handheld, designed to perform mathematical operations.
