Question

Numbers like 100,1000,10000,100000,101ect are whole numbers or natural numbers because whole numbers have zero and natural numbers don't have zero.

Answer 1

We must understand that:
Natural numbers are the set of numbers { 1,2,3,4,5,6,7,8,9,10,11.............upto infinity}
Whole numbers are the set of numbers { 0,1,2,3,4,5,6,7,8,9,10,11............upto infinity}
Whole numbers are the set of natural numbers along with the number Zero.
However, natural numbers do not include the single number 0 does not mean that the DIGIT zero cannot be used in any whole number.

ie 0 is a whole number but not a natural number.
But 10 is both a whole number and a natural number.

Hence numbers like 10,100,1000 etc are both natural numbers and whole numbers.

Hope this helps :)
