### Scientific Calculator – History

The first scientific calculator that integrated all of the fundamental features of a scientific calculator was the Hewlett-Packard HP-9100A, released in 1968.

The HP-9100 series was built exclusively from discrete transistor logic without integrated circuits, and was the first calculator based on reverse Polish notation (RPN) entry. HP became strongly identified with RPN calculators from then on, and even nowadays some of their high-end calculators still offer RPN as their default input mode.

Texas Instruments, Casio and Sharp have also been major players with Casio’s FX series and Texas Instrumentsâ€™ TI-30 series being the most commonly used scientific calculator in classrooms.
