hi,

natural numbers consists of all the "counting numbers".Counting numbers means the number we use to count, starting from 1 to endless.In natural numbers every number has a succesor and predicisor but 1 does not have predicisor so to get a predicisor for 1 we use whole numbers in whole numbers it has 0 and that is the predicisor of 1 .SO DIFFERENCE BETWEEN SMALLEST WHOLE NUMBER AND SMALLEST NATURAL NUMBER IS THIS.....

THANKS HOPE YOU UNDERSTOOD !!! THUMBS UP
