If you ever use Google to solve math problems, you may start using it even more now. If you didn't use Google to solve math problems, you may want to consider starting. Google has launched a new scientific calculator feature, which appears when you enter such a problem in the search box.
As you can see from the image above, Google will display this entire calculator interface, enabling users to conduct additional calculations right from the results page. It's pretty cool. It also works beautifully from mobile devices.
We tried it on Android and iPhone. If you you're holding your phone vertically, a smaller calculator appears, but if you hold it horizontally, the full scientific calculator takes over the screen.
Google's Matt Cutts notes that the feature is currently available at Google.com only because they want to make sure it works before rolling it out globally.
