Although every iteration of Windows comes with a pretty good calculator, you might prefer a third-party tool to perform your mathematical operations. One of the alternatives you can choose from is Calculor.

You might be surprised by the simplicity of the application but, in fact, that is one of its strong points. Unlike other applications of this kind, Calculor does not provide the standard layout you might be accustomed with. To put it another way, there is no numeric pad and no buttons to select the functions to apply. Instead, you get an editable text field that you can use to write your mathematical expression.

As you begin typing in this field, Calculor displays the answer and, with every number or operator that you add, the result is updated. In fact, this is the utmost feature of Calculor, as it is designed to deliver a lightweight alternative to the Windows calculator that enables you to type in equations and get the result on the spot.

Calculor recognizes popular constants used in maths, such as pi. Moreover, you can insert trigonometrical, and other such functions inside the equation and Calculor will calculate their value.

Although it might not be as powerful as other scientific calculators out there, Calculor is a handy tool to have around if you need to perform computations quickly.
