Google Calculator – and many un-well-known Features

How many of you know that Google is also a built-in calculator in its search box?

Try enter this in the google search box and see what happen.
Enter: 5+2*2

And it will give you the exact answer of the calculation u requested.
Answer is 5 + (2 * 2) = 9.

The site is also intelligent enough to accept complicated mathematic expressions such as 160 pounds * 4000 feet in Calories. It will give answer as (160 pounds force) * 4 000 feet = 207.390891 kilocalories

I admit I never knew this feature in Google before till today.
