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.
What are Integers?
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.
