In many Casio calculator models, a number's cube root can be determined by simply pressing SHIFT X^3, then inputting the number to be calculated. In the models without this feature, the cube root is determined by pressing the number 3, SHIFT, then the upward arrow key (^), followed by the number.

The Casio FX 115 MS is one model with the feature that allows a user to directly find a cube root. Other models, while requiring more key presses, also allow the user to find any root of a desired number. For example, to find the fifth root of -243, press the number 5, SHIFT, then the upward arrow key (^), followed by -243. In this case, the answer is -3.

Other Casio calculator models, such as the fx-991 MS and the fx-991 ES, have advanced functions that include solving standard deviations, complex number calculations, quadratic equations, linear calculations of up to three unknowns, and differential and integral calculus computations. Moreover, they also have a metric conversion feature.

The Casio company was founded by Tadao Kashio in 1946 and released the first electric compact calculator in 1957. Casio reached one million unit sales in 1972 and ten million in 1974. The aforementioned first electric compact calculator, dubbed the 14-A, is on display at the National Science Museum in Japan.
