Calculator

Calculator is a lightweight application you can use to perform basic and scientific calculations in a simple and intuitive interface. It supports modulo, square and cube of numbers, square root, natural logarithm, base e logarithm, and others.
The tool comes in handy to math students who are looking for more options than the ones offered by Windows Calculator.

Requires .NET Framework to work properly

The whole package is based on a single .exe file that can be saved anywhere on the disk and just double-clicked to launch the program. Therefore, it's possible to copy the file to a USB flash drive to directly deploy it on any PC.
However, you should make sure to download and install .NET Framework unless you already have this platform, because the app was developed with the aid of this software framework.

Basic and advanced math operators

The user-friendly interface consists of just one window, which can be extended by ticking the Scientific box. Standard calculations include addition, subtraction, division and multiplication. There are also two buttons available for clearing everything (C) and for erasing the previous character (BS).
However, it's not possible to type the numbers and operators on the keyboard, as it seems that this feature isn't implemented into Calculator. Instead, you have to click them.
In addition to the previously mentioned advanced functions, the software program supports integer values, inverse, cube (or third root) of a number, any number of root of a number, factorial, as well as three trigonometrical functions: sine, cosine and tangent of angles. Descriptions about each button are shown when hovering the mouse cursor over it.

Easy-to-use scientific calculator

All things considered, Calculator facilitates a quick and easy method of calculating mathematical expressions using both standard and advanced operators. Although it hasn't been updated for a while, it worked smoothly on the latest Windows edition in our tests.
