Windows comes with a rudimentary calculator, suitable for adding, subtracting and multiplying. It’s basic, with not much functionality, not to say even ease of use or may even actually reduce your productivity in calculation. However, there is a lot of alternative to the default Windows calculator, where you can download for free, some even to use permanently for free.
