Integers
• Integers are the set of all
whole numbers and their
opposites.
• Integers can either be negative(), positive(+) or zero.
• The integer zero is neutral. It is
neither positive nor negative, but
is an integer.
• Integers can be represented on a
number line, which can help us
understand the valve of the
integer.
Positive Integers
• Are to the right of zero.
• Are valued greater than
zero.
• Can be expressed using
words such as up, gain or
profit.
• The sign for a positive
integer is (+), however the
sign is not always needed.
• Meaning +3 is the same value
as 3.
Negative Integers
• Are to the left of zero.
• Are valued less than
zero.
• Can be expressed using
words such as down,
below or loss.
• The sign for a negative
integer is (-). This sign
is always needed.

Zero is neither positive
or negative
Negative integers
are valued less than zero,
and are always to the left of
zero.
Positive integers
are valued more than zero,
and are always to the right
of zero.
The “net worth” of
opposite integers is
zero.
Opposite Integers
• Opposite integers always have a “net worth” of
0. This is called the ZERO PRINCIPAL.
• Opposite integer have the same “absolute value”, meaning
the distance from the points on a number line to zero is the
same.
• This can be referred to as the integers magnitude.
