Want to add up a list of numbers, convert from miles to kilometers, or evaluate some other mathematical expression? Instead of using a piece of paper, your calculator, or a computer math software program, you can now solve mathematical problems with Google's built-in calculator function.

Simply enter the expression you'd like evaluated in Google's web search box and click the ENTER key or click the "Google Search" button.


The Google Calculator Quick Reference (Cheat Sheet) by Nancy Blachman provides a nice summary of some of Google's calculator features.

Once you have a result, you can use your browser's Copy feature (usually on its Edit menu) to copy the result. Then you can paste it into another program, a box in a form on another web page, and so on.
