Do you know that you have a very cool and intelligent scientific calculator available a click away which is extremely fast and lightweight? It is the web search giant Google which has inbuilt calculator facility in Google Search.

To use Google Search as calculator, simply type your mathematical expression in google search bar. It supports various mathematical functions like factorial, logarithm, trigonometric, calculating combinations, power, percentages etc. and of course normal arithmetic expressions

For example:

1. To evaluate 64+90/(89 +30)*6 , search for it on google and you’ll get the value. Along with regular arithmetic operators, modulo(remainder) operator(%) is also available.
2. For calculating percentages use % of operator e.g. 25 % of 1000
3. Exponential operator (^) can be used as x^y to calculate x to power y.
4. For square root use sqrt(number) e.g. sqrt(10), to calculate yth root of x, for example, use 6th root of 1000 as your search query.
5. Searching for tan(45 degree) will display value of tan(45 degree) in first result, similarly, you can use sin and cos. If you search for tan(45), then it’ll calculate value in radians.
6. To evaluate logarithmic values you may use log(some value) for log to base 10 and ln(some value) for log to base e. e.g. Evaluate log(100).
7. For factorial of a number simply enter number followed by !(factorial sign), e.g. searching for 5! will return 120.
8. For calculating value of ⁿC_r i.e .no of ways for choosing r elements out of n, use n choose r e.g. 10 choose 4 for ¹⁰C₄.

Besides these mathematical features, you can also convert units. e.g. searching for 1 barrel in litres will give you number of litres in a barrel.

You can also use expressions like 5 volts * 10 ampere. It’ll return result in appropriate units as below.
