CompCalc

Your home computer heavily relies on math operations. In fact, processing speed is also determined by the number of calculus the PC can perform, and it can easily help you out in solving complex expressions. In this regard, CompCalc comes as a lightweight, but powerful tool to instantly display results for math operations on different branches.

One of the application’s main advantages is portability, thus enabling you to easily carry it around on a thumb drive in case your daily activities are closely tied to math. This also means that you can run it right after download since no installation is required, while system registry entries don’t need to be modified to ensure functionality.

Running it might leave you scratching your head for a while, mostly because it doesn’t really resemble a common calculator. There is a sample expression already there with the results displayed so you get an idea of how input needs to be performed, and how output is displayed.

Input needs to be done through the keyboard, while advanced expressions rely on writing down specific triggers, such as sin, cos, and so on. The only available option is to choose the letter to represent the imaginary component, which can either be i or j.

On the bright side, there’s a rich help file filled with descriptions and examples to help you out. Although it can be a little tricky at first, at least until you learn the writing style, the application can solve quite the variety of expressions. These include and are not limited to arithmetic, powers and inverses, trigonometric, hyperbolic, constants, and complex numbers.

Taking everything into consideration, we can say that CompCalc might not be the easiest tool to learn, but is sure to deliver the right result. With enough time spent with documentation, you’re able to easily write complex expressions covering nearly all math branches, making it worth your while overall.
