Search Engine Calculator

Did you know you could type in a math problem in a search engine box and get the answer. Almost everyone has a seach box somewhere close by. Try typing in "20% of 150" and see what the answer is...
I've tried it at Google and Yahoo. There is more info about Google's calculator here.
Search boxes are more useful than ever. Check out what all you can type into these little boxes. From UPC codes to airport codes, math problems to patents.
