  3. 7 + (-9) +15 + (-12) = 1

  4. -4 – (-10) =

  5. -4 – (-10) = 6

  6. y – (y + 6) =

  7. y – (y + 6) = y – y – 6 = -6

  8. (y + 2) subtracted from (y-17) =

  9. (y + 2) subtracted from (y-17) = (y-17) – (y +2) = y - 17 –y – 2 = -19

  10. | -2/5| - |1/5| =

  11. | -2/5| - |1/5| = 2/5 – 1/5 = 1/5

  12. 9(3n-2) =
