Google’s a supercomputer! With Google toolbar, these can be as handy as they get.
To get the value of pi:
pi // Google spits pi = 3.14159265
Add them up (and don’t worry about overflow):
62385761827351234125236 + 29893847592638741692387568
Calculate the product (same as above):
854736820183475 * 29347568389187
You get the idea. And of course you can subtract and divide. Just use the basic arithmetic symbols: +, -, *, /.
Basically, Google is just a bunch of geeks and anything that’s valid across major programming languages may be used in the search phrase to do a basic mathematic calculation. For more examples, to get the mod of 23 out of 5:
23 % 5 // returns: 23 mod 5 = 3
Get the square root:
sqrt 4 // Google returns sqrt(4) = 2
Get the nth root:
3rd root of 1000 // returns: 3rd root of 1000 = 10
Get the square:
4 squared // Google returns 4 squared = 16
Get the reciprocal:
reciprocal of 7 // returns: reciprocal of(7) = 0.142857143
Get the power of 10:
10^3 // returns: 10^3 = 1 000
All those trigonometric functions commonly seen in programming languages are all implemented in Google search: sin, cos, tan, sec, csc, cot, arcsin, arccos, arctan, arccsc, etc.
ln, log, lg, exp
6! // returns: 6 ! = 720
