  1. Properties Beat the Computer Drill

  2. Directions • A slide will appear showing an equation which illustrates a property. • Say the property aloud before the computer can answer (6 sec). • You will hear a sound when the slide changes.

  3. a + b = b + a

  4. Commutative Property for Addition a + b = b + a

  5. ab + ac = a(b + c)

  6. Distributive Property ab + ac = a(b + c)

  7. a  b = b  a

  8. Commutative Property for Multiplication a  b = b  a

  9. a  1 = a

  10. Multiplicative Identity Property a  1 = a

  11. a + 0 = a

  12. Additive Identity Property a + 0 = a

  13. (a  b)  c = a  (b  c)

  14. Associative Property for Multiplication (a  b)  c = a  (b  c)

  15. (a + b) + c = a + (b + c)

  16. Associative Property for Addition (a + b) + c = a + (b + c)

  17. a + (-a) = 0

  18. Additive Inverse Property a + (-a) = 0

  19. a(b + c) = ab + ac

  20. Distributive Property a(b + c) = ab + ac

  21. a  0 = 0

  22. Multiplicative Property of Zero a  0 = 0

  23. a  = 1 1 a

  24. 1 a  = 1 a Multiplicative Inverse Property

  25. If x = b, then x + c = b + c

  26. Addition Property of Equality If x = b, then x + c = b + c

  27. If x = b, then x  c = b  c

  28. Multiplication Property of Equality If x = b, then x  c = b  c

  29. a = a

  30. Reflexive Property of Equality a = a

  31. If a = b, then b = a

  32. Symmetric Property of Equality If a = b, then b = a

  33. If a = b, and b = c, then a = c

  34. Transitive Property of Equality If a = b, and b = c, then a = c

  35. If x = 3, then 5x = 15

  36. Substitution Property of Equality If x = 3, then 5x = 15

  37. Good Job!
