SAME SIGNS JUST ADD !! ADDITION OF INTEGERS 8 + 2 = 10 -8 + (-2) = -10 4 + 7 = 11 -4 + (-7) = -11 8 + 2 = 10 -8 + (-2) = -10

DIFFERENT SIGNS THE GREATER ABSOLUTE VALUE!! IN THIS CASE: -7 SUBTRACT THE ABSOLUTE VALUES!!! 4 + (-7) = |-7| - |4| = 7 - 4 = 3 USE THE SIGN OF THE NUMBER WITH THE GREATER ABSOLUTE VALUE!! IN THIS CASE: -7 SO….. 4 + (-7) = -3

18 + (-5) = 13 - 8 + (-3) = -11 16 + (-9) = 5 -12 + (-4) = -16 EXAMPLES 18 + (-5) = 13 - 8 + (-3) = -11 16 + (-9) = 5 -12 + (-4) = -16 9 + (-13) = - 4
