What Are The Rules For Adding Integers


Before we begin, here are the rules for Adding Integers:
  • Two integers added together with the same sign produces a result with the same sign.
  • Add two numbers integers together with different signes produces a result with the sign of the larger number.

Adding integers examples:

  • Adding Positive Numbers:
    (a) 5 + 1 = +6 = 6

  • Adding Negative Numbers:
    (a) -5 + (-1) =
        -5 - 1 = -6


    (b) -5 + (-1) =
        -(5 + 1) =
        -(6) = -6


  • Adding Positive and Negative Numbers:
    (a) -6 + 14 =
        14 - 6 = 8


    (b) -6 + 14 =
        +(14 - 6) =
        +(8) = +8 = 8


    (c) 7 + (-11) =
        -(11 - 7) = -4
