0 is the additive identity.
1 is the multiplicative identity.
2 is the only even prime.
3 is the number of spatial dimensions we live in.
4 is the smallest number of colors sufficient to color all planar maps.
5 is the number of Platonic solids.

There are an infinite number of integers.
The set of integers is countable.
The set of integers is equivalent to the set of counting numbers is equivalent to the set of whole numbers is equivalent to the set of rational numbers (ie., they all have the same number of elements).
An integer is positive, negative, or zero.
An integer is prime or not prime.
An integer is composite or not composite.
The integers are ordered.
There is NOT an integer between any two integers.
The set of integers is closed under addition, subtraction, and multiplication.
The set of integers is NOT closed under division.
The composition of a rational number includes two integers.
God invented the counting numbers and man invented all the others...

Did you know that the cardinality of the set of integers is the same as that of the set of natural numbers? Z = {. . . -2, -1, 0, 1, 2, . . .} is the same "size" as N = {1, 2, 3, 4, . . .}. It's true.

Did you know you never really subtract negative integers? You always add the opposite.
