Summator vs Intuitive Calculator

The program was conceived as a calculator for calculating the cost of the check. Put it in the cart the product and drive its value. The program remembers and outputs the result. Of course, you can count on a ordinary calculator. But, with the usual calculator, it is likely to make a mistake or lose the result in the middle of the list. The accumulator holds not only stores the sum, but the list of entered numbers. So to be mistaken difficult, and to correct easily. And the function of simple calculator is present.

A calculator that is designed to be intuitive to use and understand. - Easily undo, redo, copy, and paste equations - Swipe on the keyboard keys to access additional functions - Shows you exactly where calculation errors occur and why - Shows you which functions and operators apply to which numbers so you never enter an equation in the wrong way again - See equations the way that you would write them - Use in simplified four-function or full scientific modes - Easily look through previous equations reusing their results or the equations themselves - Supports physical keyboards Calculation functions: - All of the standard, inverse, and hyperbolic trigonometry functions - Can generate random numbers - Probability functions - Rounding operators - Factorial - Summation and product
