The set of counting numbers is the positive integers. The set of whole numbers is the positive integers plus zero. The term "natural numbers" has been used interchangeably with both of those sets.
Natural numbers are actually closed under addition. If you add any two if them, the result will always be another natural number.
Since there is an infinite number of real numbers and an infinite number of natural numbers, there is not more of one kind than of another.
Natural numbers are the same as counting numbers, but the term positive numbers means something else. Natural or counting numbers are positive integers, but the category of positive numbers includes both integers and fractions, as long as they are greater than zero.
even numbers are exactly divisible by two. ie. they do not give a remainder when divided by 2. natural numbers are positive integers starting from 1. even natural numbers are a combination of both.. eg. 2,4,50 etc the term positive is not required for these numbers because, natural numbers are positive !... so positive 'natural number' is like saying ' approximated estimate '..
