Google, once again trying to be the one-stop-shop for all of your knowledge needs, has added a 34-button calculator to search results. Now, instead of just spitting out a text answer when typing in a math question, you will be able to process sines and cosines, tangents and logarithms, as well as simple addition and subtraction.

Google had given no heads up about this change, but an official Google Twitter account posted that they had rolled out the latest stage, 3.9, of its Panda algorithm last night. It's not clear whether or not the two events are linked. This calculator is just one feature in the past months designed to change Google away from just being a search engine.

Now what they really need to add is graphing capability. Then college and high school students around the world could rejoice in the fact that they could leave their graphing calculator at home and still easily have access to one.
