Calculator

One of the first methods to use a computer was for math calculus, since results are instantly delivered. This is still a common practice, with modern calculators capable of solving advanced expressions. However, simple alternatives like Calculator can provide just the right flexibility for quick, financial calculus.

Can be used on the go

With no installation required, you can go ahead and run the application right after download is done. This means that you can carry it around on a thumb drive to use on other computers besides your own, without having to worry that stability is affected, because registry entries are not modified in the process. However, you do need to make sure that Java Runtime Environment is installed on the target PC.
The core function of the application is to provide a platform for quick, and easy math calculus, similar to what the default Windows calculator already does. In fact, this application is rather poorly equipped, compared to the one Windows puts at your disposal, first of all because of the lack of an advanced set of expressions, and operators.

Can only use basic operators

The visual layout is the standard display of a calculator. The numerical pad can be used for input, but keyboard is also supported. What’s more, the large buttons also makes it easy to operate from touch-enabled devices, which is possible considering it relies on Java to function.
As mentioned above, you’re only able to perform the basic of math operations. You find options to add, subtract, multiply, divide, or extract the square root. Unfortunately, operation history is not tracked, so you need to manually copy the result of each operation if you need a detailed process, even with basic functions, and operators.

On an ending note

Bottom line is that multiple daily activities rely on simple math calculus, and Calculator wants to be a straightforward, portable alternative to the default Windows tool. Unfortunately, it provides little flexibility when it comes to the range of operations you can perform, since advanced operators are not at your disposal.
