Integers
Integers are
whole numbers
that describe opposite ideas in mathematics.
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.Slide13
So… why do we need negative and positive integers? Slide14
You can use integers to describe opposite situations. For example:
Positive Integers
Depositing money in a checking account
Elevation above sea level
Any temperature above zero
Yardage gained in football
Negative Intege
rs
Withdrawing money from a checking account
An elevation below sea level
Below zero temperatures
Yardage lost in footballSlide15
Positive Integers
Are to the right of zero
Are valued greater than zero.
Express ideas of up, a gain or a profit.
The sign for a positive integer is (+), however the sign is not always needed.
Meaning +3 is the same value as 3.Slide16
Negative Integers
Are to the left of zero
Are valued less than zero.
Express ideas of down or a lose.
The sign for a negative integer is (-). This sign is
always
needed.Slide17
Negative integers
are valued less than zero, and are always to the left of zero.
Zero is neither positive or negative
Positive integers
are valued more than zero, and are always to the right of zero.Slide18Slide19Slide20Slide21Slide22Slide23
