Scientific calculators have enabled faster and more accurate calculations by reducing errors from hand calculations. The first scientific calculator was developed in the early 20th century, with limited display and functions. In the 1940s and 1950s, early computers and calculators were created that could perform more advanced numeric computations and functions. As demand increased, calculators gained new designs and features like trigonometry and coordinate systems to handle different math problems. Today, scientific calculators remain important tools for students and scientists to graph functions, operate on variables, and solve geometry and area problems.
