One of the things I love about Google is that they keep adding more and more stuff you can do with their site. They seem to have a playful laboratory sense of doing things.
They create new tools and then without much fanfare put em on the site for all to join in on the fun.
Here are two new ones that I use a bunch
Definitions: I know there are plenty of dictionary sites and ways to get definitions but here is my favorite.
At the Google home page type, define:XXXX (XXXX is your word) Hit enter and there you have it. 5 or 6 definitions pop up.
Calculator: Type a math problem or even a math question into the Google search bar and out pops the answer.
5+5, square root of 3492, pints in a gallon.
Give it a try.
