Desmos - a better, free, online calculator

A Better Calculator is a new, free, online graphing calculator from Demos (who also offers a service to create online interactive media). There is nothing to download as it runs online. It is easy to use, full color, full functioned. You can share your work online or even share it with others (like your students) or students can share it with their teacher.

The screen is nicely laid out with the functions and expressions on the left and the graph on the right. There is help available and even some examples to look at.

It is also now built with HTML5 so it works on all devices, including the iPad.

This could easily replace all those expensive graphing calculators that students have. I was able to access and use this on my smartphone browser also.

Free online scientific calculators

Calculators are a necessary tool in science and math classes. But, they don't have to cost the students anything.

First, there are a ton of free calculator apps available for every smartphone (iOS, webOS, Android, BB, Windows) so any student with a smartphone or PDA can get one on there.

Second, there are some free downloadable calculators, such as Microsoft Math and most computers have a built in calculator.

But, free, online calculators are also a great resource for educators and students. There are calculator extensions for Chrome and Firefox that students can use on their computer or through their Google account.

Here are some free online calculators that I like:

Web 2.0 Calc.com - free online scientific calculator. Available on mobile browser. Can be embedded in your own website or blog too.
