NATURAL numbers

They are called the natural numbers because they are the first to have crossed paths with human intellect . Think about it: these are the              
numbers we count things with. So our ancestors used these numbers first to count, and they came to us naturally! Hence the name
       NATURAL!!! 
  The natural numbers form a subset of a larger class of numbers called the integers. I have used the word  SUBSET. From now onwards we will just think of SET as a COLLECTION OF THINGS.
