How do we calculate the century effectively?

A century is defined mathematically is the value of '100'. A century is used mainly when we speak about year's and also used in the sport cricket. In cricket if a player scores 100 runs, it means he made a century and is considered to be a milestone. 

Commonly we are asked in what century we live in. In order to calculate this we divide the year by 100. drop the decimals and add 1. 

Let's demonstrate this by an example: 

If we had to calculate the century in the year 1960 is, it will be done as follows: 

`1960/100 = 19.6`

Now we have to drop the decimals:

`19`

Now we have to add "one' to determine the century we in: 

century the year 1960 is = 

Therefor the year 1960 was in the 20th century.
