The HP 38G (F1200A, F1892A) is a programmable graphing calculator by Hewlett-Packard (HP). It was introduced in 1995 with a suggested retail price of US$80 (equivalent to $160 in 2023). HP credits a committee of eight high school, community college, and university teachers with assisting in the design of the calculator.
The calculator is derived from and the hardware is based on the more powerful science/engineering oriented HP 48 series of machines.
Unlike the HP 48 series, which offered both reverse Polish notation and algebraic entry logic, the HP 38G has only algebraic entry. The calculator is programmable, supporting small, interactive applications called "aplets".
