What are Integers?

• Integers are whole numbers and their opposites.
  Ex.(0, 1, 2, 3, 4)
• Integers consist of negative and positive
  numbers.
• Zero is neither negative nor positive.

4
Positive Integers

• Integers that are greater than zero.
• They will always be to the right of the zero on
  the number line.

5
Negative Integers

• Integers that are less than zero.
• They will always be to the left of the zero on
  the number line.

6
Adding Integers

• When adding integers with the same signs, add the
  two numbers and keep that sign.
• When adding integers with opposite signs,
  subtract the smaller number from the larger
  number and keep the sign of the larger number.

7
Examples of Adding Integers

• (-7) 8 1
• 15 (-23) -8
• (-11) (-5) -16

Subtracting Integers

• First change problem to addition. Remember the
  phrase ADD THE OPPOSITE!!! Change the
  subtraction symbol to addition and the number
  that follows becomes its opposite.
• Then, follow the rules for adding integers.
