  1. Adding Integers When adding integers use SADS. If the signs are the same, add the numbers and take the sign of the largest absolute value. If the signs are different, subtract the numbers and use the sign of the number with the largest absolute value. (Cover the signs to find the largest absolute value.) Example: Same sign Example: Same Sign Add Different Signs • 3 + 4 = 7 Different sign 3) (-2) + (5) = 3 • (-3) + (-4) = -7 Subtract 4) (7) + (-9) = -2

  2. Subtracting Integers When subtracting integers use Same Flip Flip then SADS. Same- keep the sign of the first number Flip- change the minus to plus Flip – changethe sign of the second number Then Same sign Add Different sign Subtract

  3. ExamplesSubtracting Integers • -3 – 1 3) -1 – (-8) = -3 + (-1) = -1 + 8 = -4 = 7 2) 5- (-2) 4) 4-1 = 5 + 2 = 3 = 7

  4. Multiplying Integers If the signs are the same your answer will be POSITIVE! If the signs are different your answer will be NEGATIVE! Examples: Examples: • 3 ·3 = 9 3) 3 · (-3) = -9 • (-3) · (-3) = 9 4) (-3) · (3) = -9

  5. Dividing Integers If the signs are the same your answer will be POSITIVE! If the signs are different your answer will be NEGATIVE! Examples: Examples: • 25 ÷ 5= 5 3) -25 ÷ 5 = -5 • (-25) ÷ (-5) = 5 4) 25 ÷ (-5) = -5
