The integers are whole numbers. It can be positive or negative.

We call the set of integer numbers " z"

z = { ...., -4, -3, -2, -1, 0, 1, 2, 3, 4, 5....}

There are unlimited integers in the set of integer numbers.

For example:

2, 3, 7, -8, 123, -745  are all integers.

1/2 , 0.5, 123.3,  12.7 , 34/7   are NOT integers.

An integer is any whole number.  That is, it is a number that has no fractional or decimal component attached to it.  For example, the number 1.5 is not an integer because it has a decimal component.  By contrast, the number 15 is an integer because it has no decimal.

An integer can be positive or negative.  It can also be zero.  The only rule is that it cannot have a fractional or decimal component.

The integer numbers are the elements of the integer set, called Z.

There are 3 kinds of integer numbers:

- positive integers: +1 ; +2 ; +3 ; ....;

- negative integers: -1 ; -2 ; -3 ; ....;

- zero: 0.

We can recognize the positive integers as being the counting numbers.

A number that is not integer is placed between 2 counting numbers.
