# Google Calculator – The Advanced Guide

The Google Calculator, unlike what people think, is a quite powerful calculator! It’s almost a shame that only geeks like my self tend to use it :roll:. That’s why I thought that I should give you some basic and advanced guidelines on how to use this online calculator.

In section **(1)** I list the commands and their functions while in section **(2)** you will find some examples. Finally in section **(3)** I will show you some **really cool operators**. ðŸ™‚

**1a) Basic Commands**

**Addition:** +

** Subtraction** –

** Multiplication:** *

** Division:** /

**Exponentiation:** ^

**Calculate Percentage:** % of

**1b) Advanced Commands**

**Square root:** sqrt(number)

** Calculate Root:** the nth root of [number]

** sin, cos etc:** trig function(number in radians)

**lg:** log(number)

** Factorial:** !

**2) Examples**

Â¤ 10% of 100

Â¤ 5^2

Â¤ 3th root of 27

Â¤ 5!

Â¤ sin(0)

I think you get the picture…

**3) Goodies**

Â¤ You can force the calculator to evaluate an expression if possible by simply using the equal sign = (Mathematical errors can of course not be applied such dividing by zero).

Â¤ With the **in** operator you can convert a certain unit to another. I use this all the time when faced with “weird” American units like inch and yards (??? ;)), shame on Amazon.com for not giving their information in SI-units. For instance if you want to know how many meters 20 yards equals you write: 20 yards in meters. Cool, heh?

Â¤ Google Calculator can understand a lot of the different mathematical constants out there, you can chose to write **c** or “speed of light”, both work. I hope you enjoyed this article, if you have any tips of your own, please share it with us ðŸ˜‰
