Integers and natural numbers
NettetMany other number sets are built by successively extending the set of natural numbers: the integers, by including an additive identity 0 (if not yet in) and an additive inverse −n for each nonzero natural number n; the rational numbers, by including a multiplicative inverse / for each nonzero integer n (and also the product of these inverses by … NettetIn elementary school teaching, integers are often intuitively defined as the union of the (positive) natural numbers, zero, and the negations of the natural numbers. This can be formalized as follows. [33] First construct the set of natural numbers according to the Peano axioms, call this .

Nettet24. okt. 2010 · The reason for doing so is because we have already created a bijection from the positive integers (natural numbers) to the positive rationals. So it only seems natural that by adding in the negative integers, we can map them to the negative rationals and thus obtain a bijection. We do this as follows:

As it can be written without a decimal component it belongs to the integers. It is a rational number because it can be written as: $$\frac{4}{1}$$ or $$\frac{8}{2}$$ or even $$\frac{-8}{-2}$$ Whereas $$\frac{1}{5}=0.2$$ is a rational number but not an integer.
