What is a Calculator?

A calculator is defined as a device or program that performs mathematical calculations.  While that straightforward definition definitely does hold true, it does not address the true purpose of a calculator: Being something that saves you tremendous amounts of time. 

Here at the Free Calculator, we are committed to saving you time. We provide you with every useful calculator you can think of. From vital physics, chemistry, and construction calculators to some that may be a little off the beaten path. If you need Ecology Calculators to lessen your carbon footprint or Sports Calculators to follow your favorite team, we have those too.

How does a calculator Work?

In developing all of our calculators, our philosophy was simple.
We wanted to make every calculation quick and painless for our users.

As previously stated, our primary goal is to save you time, so we made our calculators simple and user-friendly. All you have to do is enter you values, and you’ll get the answer. You don’t need to know any formulas. You don’t need to know any equations. It is an easy, one-step process.

Of course, if you want to learn a little bit more about the theory behind the calculator you are using, we have lots of information on each page to help you become the math whiz you always wanted to be!
