Use Google as Usefull Calculator
Google search engine is the best serch engine in the world. This ability has known a lot of people in the world who use internet. But, goole has a many hidden feature that maybe some people don’t know. Google’s Calculator is one of them.
Google’s calculator tries to understand the problem you are attempting to solve without requiring you to use special syntax. However, it may be helpful to know the most direct way to pose a question to get the best results. Listed below are a few suggestions for the most common type of expressions (and a few more esoteric ones).
Most operators come between the two numbers they combine, such as the plus sign in the expression 1+1.
| Operator |
Function |
Example |
| + | addition | 3+44 |
| - | subtraction | 13-5 |
| * | multiplication | 7*8 |
| / | division | 12/3 |
| ^ | exponentiation (raise to a power of) | 8^2 |
| % | modulo (finds the remainder after division) | 8%7 |
| choose | X choose Y determines the number of ways of choosing a set of Y elements from a set of X elements |
18 choose 4 |
| th root of | calculates the nth root of a number | 5th root of 32 |
| % of | X % of Y computes X percent of Y | 20% of 150 |
Some operators work on only one number and should come
before that number. In these cases, it often helps to put the number
in parentheses.
| Operator |
Function |
Example |
| sqrt | square root | sqrt(9) |
| sin, cos, etc. |
trigonometric functions (numbers are assumed to be radians) |
sin(pi/3) tan(45 degrees) |
| ln | logarithm base e | ln(17) |
| log | logarithm base 10 | log(1,000) |
A few operators come after the number.

Example |
| ! | factorial | 5! |
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:
You can use hexadecimal, octal and binary numbers.
Prefix hexadecimal numbers with 0x, octal numbers
with 0o and binary numbers with 0b. For example:
+ 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
