These days, just about everyone has access to a handy calculator. Most phones have a built-in calculator app, and for many everyday situations, that’s more than enough to help you out if you find yourself stuck in a traffic jam.

But not all calculators are created equal. Scientific and graphing calculators are significantly more powerful than what you would likely find by default on your home or phone.

Here are the six best online scientific calculators you can find.

web2.0calc tops the list, and for good reason. web2.0calc is a simple and easy to use scientific calculator that you can find online.

web2.0calc is great because it doesn’t just give you the answer. Each time you type an expression, it expands it for you, and then expresses the solution in different ways, such as a fraction and a decimal.
