In another expansion of its massive brainpower, Google will now add 2+2 for you:

To use Google’s built-in calculator function, simply enter the expression you’d like evaluated in the search box and hit the Enter key or click the Google Search button. The calculator can evaluate mathematical expressions involving basic arithmetic (5 2*2 or 2^20), more complicated math (sine(30 degrees) or e^(i pi) 1), units of measure and conversions (100 miles in kilometers or 160 pounds * 4000 feet in Calories), and physical constants (1 a.u./c or G*mass of earth/radius of earth^2). You can also experiment with other numbering systems, including hexadecimal and binary.
