Answer to above question is, natural numbers cannot be negative numbers because they always start from 0 and goes to any positive numbers. Negative numbers and fraction numbers cannot be included in case of natural numbers. Example: 15/17, 16/19 and 19/30 all are fractional numbers. The natural numbers are 0, 1, 120, 103, 104, 115, 610, 710, 802, 905, 1005, 1105, 1200, 1300 and so on. âNâ is used for representation of natural numbers.
To start, you have the right definition for natural numbers. For rational numbers, i.e. numbers that can be written as fractions of integers, you can define (a/b) x (c/d) = (a x c)/(b x d). If you work it out, you can prove that this definition satisfies all the properties you'd want from multiplication (i.e. it's associative, it's commutative, inverses exist, etc.)
