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.

The HP series was built entirely from discrete transistor logic with no integrated circuitsand 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.

A few have multi-line displays, with some models from Hewlett-PackardTexas InstrumentsCasioSharpand Canon using dot matrix displays similar to those found on Scientific calculator calculators.

HP became closely identified with RPN calculators from then on, and even today some of their high-end calculators particularly the long-lived HPC financial calculator and the HP series of graphing calculators still offer RPN as their default input mode due to having garnered a very large following.

Uses[ edit ] 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.
