Adding Integers

  • Adding integers using the number line
  • Adding integers using the rules:
    • If you’re adding integers with the same sign, add the absolute values and keep the sign
    • If you’re adding integers with different signs (a positive and a negative), subtract the smaller absolute value from the larger and keep the sign of the larger!

Subtracting Integers

  • Subtracting integers using the number line
  • Remember that adding a negative or subtracting a positive can both be written as subtracting.
    • i.e.  3-(+2) and 3+(-2) are both 3-2
  • Remember that subtracting a negative is the same as adding a positive.
    • i.e.  3-(-2) is the same as 3+2
    • In 3-(-2) we are taking away a negative. This gives us a positive).
