Commutative Associative and Identity Properties

What is an example of the commutative property of multiplication?

• 2b = 2c

• 2 x 2 = 4 x 1

• 2 x 4 = 4 x 2

• 4 x (1 x 2) = (4 x 1) x 2

According to the commutative property of addition, 2 + 5 equals:

• 6 + 1

• 3 + 4

• 5 + 2

• 4 + 3

The commutative property of addition states that the order of the numbers in an equation:

• Should go from smallest to largest

• Should go from largest to smallest

• Is important

• Doesn't change the sum

How could you rewrite 6 x n using the commutative property?

• n x 6

• 6 to the power of n

• n + 6

• n + 1 + 5

How could you rewrite n + 6 using the commutative property?

• n = 6

• n x 6

• n/6

• 6 + n

Which is an example of Associative Property of Addition?

• (12+3)+8=12x(3x8)
• 12x(3x8)=(12x3)x8
• (12+8)+3=12+(8+3)
• 12 + 18 = 18 + 12

Which is an example of the Associative Property of Addition?

• 7+(6+3)=7+(3x6)
• 3x4 = 4x3
• 7 + 3 = 13 + 7
• 2+(3+4)=(2+3)+4

According to the Associative Property of Multiplication, (9 x 6) x 5 =
