google inbuilt search I

have anybody searched for 224352+31237789 in google.to some it might seem be unknown that google will sum up the two numbers and returns the correct result in this case 31462141.

many if not all know that google can be used as a calculator in ever sense of it.we can use trignometric functions,unit conversion and all kinds of mathematical and algebraic equations.

Many won't know that google even recognises constants

c-speed of light

e-pie(22/7)

h-planck's constant

k-boltzmann's constant

just google for 'c' and see the result
