Dividing integers with different signs gives a ______ quotient. B. Addition of Integers: Direction: Add the following integers. 1. 13 + (-5) = 6. (-16) + (-11) = 2. 16 + 7 = 7. (-89) + 5 = 3. (-22) + (-10) = 8. (-15) + (4) + (-2) = 4. 8 + (-8) = 9. (-500) + 500 = 5. 0 + (-24) = 10. (-13) + 0 = C. Subtraction of Integers: Direction: Subtract the following integers. 1. 13 - (-5) = 6. (-16) - (-11) = 2. 16- 7 = 7. (-89) - 5 = 3. (-22) - (-10) = 8. (-15) - (4) + (-2) = 4. 8 - (-8) = 9. (-500) - 500 = 5. 0 - (-24) = 10. (-13) – 0= D. Multiplication and Division of Integers: Give the answers of the following items 1. (3) (-2) = 6. 15 ÷ 3 = 2. (-12) (-2) = 7. 20 ÷ (-2) = 3. (-9) (0) = 8. (-16) ÷ (-4) = 4. (-6) (8) = 9. (3) ÷ 0 = 5. (9)(-1) (-4) = 10. 0 ÷ 100 =
