35. Lesson 6.6.5 Algebra: Properties
Tuesday, Nov 4
Lesson Algebra: Properties

36. Algebra: Properties
Objective: To use properties to simplify expressions.

37. Algebra: Properties
Math properties are statements that are true for any number.

38. Algebra: Properties
Commutative Property (CP) - The order in which two or more numbers are added or multiplied does not change the sum or product. e.g = e.g. 3 · 2 = 2 · 3 a + b = b + a a · b = b · a The word commute means to move around.

39. Algebra: Properties
Associative Property (AP) - The way in which three numbers are grouped when they are added or multiplied does not change the sum or product. e.g. 9 + (7+ 5) = (9 + 7) · (2 · 4)= (3 · 2) · 4 a + (b+ c) = (a + b) + c a · (b · c) = (a · b) · c The word associate means group.

40. Algebra: Properties
Distributive Property (DP) – To multiply a sum by a number, multiply each addend by the number outside the parenthesis. e.g. 4 · (3 + 1) = 4 · · 1= = 16 e.g. 4 · (a + 1) = 4 · a + 4 · 1 or 4a + 4 The word distribute means to share.

41. Algebra: Properties
Identity Properties (IP) - The sum of an addend and zero is the addend. The product of a factor and one is the factor. e.g = 9 3 · 1 = 3 a + 0 = a a · 1 = a

42. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why ( 5 + 8) and (15 + 5) + 8 How can we do this?

43. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why ( 5 + 8) and (15 + 5) + 8 To determine if expressions are equal, perform the operations using the order of operations, then compare the answers.

44. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why ( 5 + 8) and (15 + 5) = 28, so 15 + ( 5 + 8) = (15 + 5) + 8, AP

45. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why. ( ) - 3 and 20 – (12 – 3) Do this on your own.

46. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why. ( ) - 3 and 20 – (12 – 3) ≠ 11 AP is not true for subtraction.

47. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why and 34 Do this on your own.

48. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why and = 34 IP

49. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why. 20 ÷ 5 and 5 ÷ 20 Do this on your own.

50. Algebra: Properties
Determine if the two expressions are equivalent. If so, tell what property is applied. If not, explain why. 20 ÷ 5 and 5 ÷ 20 4 ≠ ¼ CP does not work for division.

51. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 6 + ( 4 + a) Do this on your own.

52. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 6 + ( 4 + a) AP essentially says if we have all addition or all multiplication we can remove the parenthesis.

53. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 6 + ( 4 + a) a Can we perform any operations?

54. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 6 + ( 4 + a) a = 10 + a

55. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 7 · (t · 3) Do this on your own.

56. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 7 · (t · 3) 7 · t · 3 = 21t

57. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 3 + (z + 5)

58. Algebra: Properties
Use one or more properties to rewrite each expression as an expression that does not have parenthesis. 3 + (z + 5) 3 + z + 5 = 8 + z

59. Algebra: Properties
In recent years the Kansas Jayhawks had 15 guards, 4 forwards and 3 centers on their roster. Write two equivalent expressions using the Associative Property that can be used to find the total number of players on their roster. Do this on your own.

Determine whether ( ) x 4 = x 4 is true or false. Explain.

64. Algebra: Properties
Determine whether ( ) x 4 = x 4 is true or false. Explain. False; using the order of operations, ( ) x 4 = x 4 = 158

65. Algebra: Properties
