Top 10 Technique – Google Does Math

Beyond using keywords and catch phrases to identify candidates with Google, this search engine also employs very powerful computational language that allows you to perform any type of calculation or conversion. Here are some examples.

–  4+3 displays 7
–  9-4 displays 5
–  3*7 displays 21
–  45/9 displays 5
–  5^3 displays 125 (5 raised to power 3)
–  11%5 displays 1 (the remainder after division)
–  sqrt, nth root ofx (sqrt(64) displays 8, if you need non-square roots you can use for example 3th root of 27)
–  sin, cos, arctan, tan…

Google calculator supports various trigonometric functions, expecting a radians value, that can be expressed also using the pi constant: sin(pi/2), tan (2/3*pi)

–  ln: displays natural (base e) logarithm: ln(e^5)
–  log: displays base 10 logarithm: log(100)
–  !: displays n factorial: 3!

Numbers can be entered also in hexadecimal, octal and binary base, using 0x, 0o and 0b prefixes, for example 5 +0xf+0b1001

Conversions

–  in degrees / in radians: convert radians to degrees: pi/2 in degrees or convert degrees into radians: 90 degrees in radians
–  in hex / in binary / in octal / in decimal: convert to each of the given bases: 16 in hex , 16 in octal, 16 in binary, 0×11 in decimal
–  use 2009 (MMIX) in Roman numerals
–  distance conversions: use 100miles in km , 1m in mm, but also 200000 km in light-second etc.

Examples:

–  100mph in kph
–  1 month in seconds
–  280 Kelvin in Celsius
–  50 Fahrenheit in Celsius
–  3 euros in $ or 3 euros in dollars
