A2: The various properties of Natural numbers and Whole numbers are as follows:Addition PropertyWhen two natural numbers are added, the result is a natural number. Eg: 34+145 = 179Similarly, when two whole numbers are added, the result is a whole number. Eg: 6+10= 16Subtraction PropertyThe subtraction of two natural numbers may or may not result in a natural number.Eg: 5 –12 = -9 is not natural numberBut 11– 5 = 6 is a natural numberThe subtraction of two whole numbers may or may not result in a whole number.Multiplication PropertyMultiplication of two natural numbers always results in a natural numberEg: 12 X 6 = 72 is a natural numberMultiplication of two whole numbers always results in a whole numberEx: 14 X 0 = is a whole number, where 4 and 0 are also whole numbers.Division PropertyDivision of two natural numbers may always not always result in a natural number.Division of two whole numbers may always not always result in a whole number.This is because if the result is in fraction or decimal, then they are not considered as natural or whole numbers.Eg: 4/2 = 2 is natural as well as the whole number.But 5/2 = 2.5 is neither natural nor the whole number.
