Is there anyone who do not know that Google is a search engine? Well , but then, how many know that you can use Google search box as a calculator as well?It has a hidden calculator! Oh, no! It is not just an ordinary calculator to calculate only the basic math stuff but it can calculate both the basic and advanced math problems too!

Another advantage is that, you don't have to restrict yourself to numbers! Google can understand any words and abbreviations and evaluate those expressions, too.

Like for example, you want to add 1+1 (Great! Since I’m not a genius at Maths, I can only understand such simple basic stuff as 1+1..LOL)

Type in 1+1 and click Search
Your ansnwer will show up 1+1=2

You may use words too
Like,one plus one
and your results show.. one plus one=two

You want to search for documents containing the terms you added, like for instance the 1+1,we just totaled? You can just do that and get results!

You can calculate like this too!
Next, coming to Complex Math problems…

Google can calculate more complex problems such as three to the thirtieth power,
3^30

the square root of 160
or (sqrt)

or the sine of 30 degrees.
sine(30 degrees)

You can even find the number of possible groups in a set. For instance,
24 choose 7 - finds the number of possible choices of 7 items from a group of 24 items.
And so on and so forth!

In the same manner,to calculate logarithm base 10 values, type log (100) in search box and press search button to show the result.
To calculate cos90 value, type cos(90) in search box and press search button to show the result.

Here are some other math syntax Google recognizes:
• - for subtraction
• * for multiplication
• / for division
• ^ for exponential (x to the power of y)
• % for modulo (to find the remainder after division)
• choose X choose Y fines the number of possible subset groups of Y out of the set of X.
• th root of creates the nth root of a number
• % of finds percentages X % of Y finds X percent of Y.
• sqrt finds the square root of the number that follows
• ln logarithm base e
• log logarithm base 10
• lg logarithm base 2
• ! factorial - This must follow the number you wish to factor.
