I did not know if I can use Google search engine as calculator, this because I did not pay attention to the features that Google offered, and I’m not saying that Google is better search engine than others. Every blogger have his/her favorite search engine, but to know and learn something new is always better for me and maybe you’ll agree with my opinion too. Ok let’s start.
Now, in search box just type any number and operator function and then hit search button, here list of operators from Google.

Operator \\ Function\\Example:

2. - \\subtraction \\ 13-5
3. * \\ multiplication\\7*8
4. / \\ division \\ 12/3
5. ^ \\ exponentiation (raise to a power of)\\ 8^2
6. %\\ modulo (finds the remainderafter division)\\ 8%7
7. choose \\ X chooseY determines the number of ways of choosing a set of Y
elements from a set of X elements \\18 choose 4
8. th root of \\ calculates the nth root of a number\\ 5th root of 32
9. % of X % of Y\\ computes X percent of Y\\ 20%of 150
10. sqrt\\ square root\\ sqrt(9)
11. sin\ cos\ tan\\ trigonometric functions (numbers are assumed to be radians)\\sin(pi/3) \tan(45 degrees)
12. ln\\ logarithm base e\\ ln(17)
13. log\\ logarithm base 10\\ log(1,000)
14. !\\ factorial\\ 5!

To make you an advance user here other good things to know:
You can force the calculator to try and evaluate an expression by putting an equals sign (=) after it. This only works if the expression is mathematically resolvable. For example, 1-800-555-1234= will return a result, but 1/0= will not.

Parentheses can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3 causes the addition to happen before the multiplication.

The in operator is used to specify what units you want used to express the answer. Put the word in followed by the name of a unit at the end of your expression. This works well for unit conversions such as: 5 kilometers in miles.

You can use hexadecimal, octal and binary numbers. Prefix hexadecimal numbers with 0x, octal numbers with 0o and binary numbers with 0b. For example: 0x7f + 0b10010101.

The calculator understands many different units, as well as many physical and mathematical constants. These can be used in your expression. Many of these constants and units have both long and short names. You can use either name in most cases. For example, km and kilometer both work, as do c and the speed of light.
Now, you know what I know that some blogger don’t know :)
