Negative numbers, positive numbers, and zero are all examples of integers. Real number examples include 1/2, -2/3, 0.5, and 2. Integer Examples: -4, -3, 0, 1, 2. Every point on the number line corresponds to a different real number. The natural numbers, also called counting numbers or positive integers, are the numbers $$1,2,3,4,5,$$ and so on, obtained by adding $$1$$ over and over again. The set $$\{ 1,2,3,4,5, \cdots \} $$ of all natural numbers is denoted by the symbol $$\mathbb{N}$$.There is no difference.
