GRE Calculator

GRE Calculator is a lightweight software application whose purpose is to help you perform math calculations on the breeze, such as addition, subtraction, multiplication, and division.

Minimalistic looks and basic functionality

You are welcomed by a window that provides general information about the function of each built-in parameter. In order to accomplish the math operations, you are required to press the “Calculator” button. On the downside, if you close the main panel, which displays additional data, the calculator is automatically closed, so you need to have both windows opened at the same time.
The calculator sports a simple and intuitive layout that gives you the possibility to input data using your mouse or keyboard.
The result cannot be copied to the clipboard, so you are not able to paste them into other third-party utilities. On the downside, the tool doesn’t offer support for trigonometric functions, like sine, cosine, and tangent.
Additionally, you are allowed to change the sign for the currently displayed number and compute square roots. Since there aren’t any configuration settings, even less experienced users can learn to configure the entire process with minimum effort.
During our testing we have noticed that GRE Calculator accomplishes a task very quickly and without errors throughout the entire process. It leaves a minimal footprint on system resources, so it doesn’t hamper computer performance, nor interfere with other programs’ functionality.

Bottom line

To sum things up, GRE Calculator seems to be the right choice for users who are looking for an easy-to-use calculator that comes bundled with basic functions.
