Calculator

Calculator is a lightweight software application developed specifically for helping you work with a simple calculator that allows you to perform several mathematical operations, namely addition, subtraction, multiplication, and division. It can be deployed on all Windows versions out there, provided that you have the Java working platform installed on the target computer.

Drop it on pen drives

The utility is portable which means that you can get access to its GUI without having to go through an installation process. A simple double-click on the executable file is sufficient.
What’s more, you can opt for storing the tool on USB flash drives or other removable devices to carry it with you all the time. Plus, you may run it without having to possess administrative privileges.
It’s easy to get rid of it in case you no longer need it because it does not leave entries in your Windows registry and generate additional configuration items. You can delete the file that you have downloaded from the Internet.

Minimalist design and a few calculation parameters

Calculator sports a simple and intuitive layout that embeds all configuration parameters within a single window. A help manual is not comprised in the package. However, you do not need one in order to decode the setup options because they look very easy to work with. No extra configuration settings are hidden under the hood.
The application offers you the possibility to perform addition, subtraction, multiplication, and division operations. It does not offer support for trigonometric functions like percentage or square root of a number, sine, cosine, tangent, and cotangent.
Tests have pointed out that Calculator carries out tasks quickly and without errors. It remains light on system resources so the overall performance of the computer is not affected. You may keep it running in the background.

Final ideas

All in all, if you are looking for nothing more than a simple calculator that comes bundled with basic features, you may give Calculator a try and see what it can do for you. It is suitable especially for less experienced users.
