  2. (-9) \times (-9)
  3. (-10) \times 18
  4. 7 + (-11)
  5. (-13) \times 16
  6. 18 - (-5)
  7. (-75) \div 15
  8. (-36) \div (-6)
  9. (-16) \times (-10)
  10. (-15) - 4
  11. (-19) - (-8)
  12. 14 + (-12)
  13. (-56) \div 7
  14. (-4) - (-14)

    15. If b = 16,\ y = -20,\ z = -16 , evaluate the expressions below, without a calculator:
  15. z + b
  16. 3z
  17. y^{2}
  18. y - b
  19. 3b - z
  20. 2y + 2z
  21. zby
  22. \displaystyle{\frac{zy}{b}}
