Google just added a calculator to its search results. Give it a try. Open up your favorite web browser, and then go to Google’s homepage at: www.google.com Then in the search box, for example type in your equation, such as “2+2=” and hit enter, and you will now have the Google calculator on the top of your web browser. Better yet, in the search box, just type in “cal”, short for “calculator”, and the Google calculator will automatically appear. You will have to click the buttons on the Google calculator in order to use it, meaning that the number keys on your keyboard won’t work.
