Basic Calculator

Basic Calculator is a feather-light application that facilitates a simplistic mathematical calculator for casual PC users. You can resort to it if Windows Calculator is faulty, for example.

The program's wrapped in just one .exe file that can be copied to a custom directory on the disk or stored on a USB flash drive to be able to launch it on any computer with as little effort as possible.

It doesn't insert new entries into the Windows registry, nor does it generate extra files and folders on the disk, unlike installers. However, it cannot work without .NET Framework. Newer Windows iterations come bundled with this software framework, though.

When it comes to the interface, Basic Calculator is definitely user-friendly. There are no complex options or customization properties available.

It shows a rectangular frame that encompasses a standard calculator, where you can perform additions, subtractions, multiplications and divisions.

The decimal operator is supported, and it's also possible to clear results to make new calculations. Results can be selected and copied via the Ctrl+C hotkey or right-click menu.

Unfortunately, Basic Calculator doesn't even equal Windows Calculator in terms of settings. For instance, it doesn't implement a feature for showing expressions to keep track of inputted numbers.

Moreover, the number keys on the keyboard aren't functional. Instead, you can use the arrow keys to navigate buttons and press Enter or Spacebar to make a selection. Although it's possible to use the tool without a mouse, it's also inconvenient.

All things considered, Basic Calculator is far from becoming your go-to software utility for evaluating mathematical expressions. Nevertheless, it lives up to its name and can be easily tackled for standard operations. The source code is available and can be studied by programmers or those interested in coding.
