**What are Integers?**

An integer is a whole number (not a fraction) that can

be positive, negative, or zero. Therefore, the numbers 10,

0, -25, and 5,148 are all examples of integers. Integers

cannot have decimal places.

When two integers are added, subtracted, or multiplied, the result is

also an integer. However, when one integer is divided into another,

the result may be an integer or a fraction. For example, 6 divided by

3 equals 2, which is an integer, but 6 divided by 4 equals 1.5, which

contains a fraction. Decimal numbers could by rounded to produce

an integer result.

**Integers are sign numbers**

Definition of sign numbers: a number preceded by a positive or

negative sign.

note: the number zero is an integer but it is not positive or negative
