Which property of multiplication is shown below:
1 × 83 = 83

• Commutative Property
• Associative Property
• Identity Property
• Zero Property

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

• Should go from least to greatest
• Doesn't change the product
• Should go from greatest to least
• Is always important

Rewrite (9 x 6) x 5 using the associative property.

• 270
• 9 x 30
• 9 x (6 x 5)
• 5 x 9 + 5 x 6

States that the product of the number and 1 is that number.

• Identity Property of Zero
• Identity Property of Multiplication
• Identity Property of Addition
• Multiplicative Property of Zero

Which of these illustrates the associative property of multiplication?

• 3 x (2 x 7) = (3 x 2) x 7
• 6(3 + 1) = (6 x 3) + (6 x 1)
• 4 x 23 = 23 x 6
• 5 x 0 = 0

• A
• B
• C
• D

Find and explain the error.    
 5 - 3 + 2
     5 - 5
        0

• There is no error.
• Addition was done first and you should have subtracted first
• There is a subtraction error
