Stupid Google trick #1782
This has probably been around for a while, but I only noticed it last week.
Make sure you're using a browser or toolbar with "Google suggest" enabled. This is the feature that brings up suggested searches as you type. For example, if you type "king cr" it drops down a box showing (among others) "king crimson" and "king crab".
Now type "123+456" and wait a moment for the suggestions to arrive. It will show a single suggestion, containing "=579". Your search box is now a calculator... no need to hit return or anything.
For the math geeks: type "e^(pi*i)".
