Calculator Apparatus takes the scientific calculator to the next level. Unlike a regular scientific calculator, you can give Calculator Apparatus an entire mathematical expression to evaluate, instead of doing only one calculation at a time. Supported functions include arithmetic, exponents, logarithms, hyperbolic functions, and trigonometric functions in degrees, radians and gradients.

You have the option of output in regular or scientific notation, and rounding options for both a constant number of decimal places and significant figures. What’s more, all of your calculations are saved in history, even after clearing them.
