Indicate which property is illustrated in Step 2.
Step 1 8 + (5 + 8) + 0 = 8 + (8 + 5) + 0
Step 2 = (8 + 8) + (5 + 0)
Step 3 = (8 + 8) + 5
Step 4 = 16 + 5
commutative property of addition
identity property of addition
associative property of addition
distributive property

Best ResponseYou've already chosen the best response.0Hi, I can help you with this. They're asking what was used in going from 8 + (8 + 5) + 0 (*) to (8+8) + (5 + 0) (**) First question: did the ORDER the #s are listed change in going from (*) to (**)?

Best ResponseYou've already chosen the best response.0Here's what I mean: In (*), the numbers (listed from left to right) are: 8, 8, 5, 0 In (**), they are: 8, 8, 5, 0 Did the order change? Did any #s change places?

Best ResponseYou've already chosen the best response.0Good. So, it's not a commutative law, because "commuting" has to do with "changing places". Now, did the GROUPING of the #s change? LIke, in 8 + (8+5) + 0, the 8 and the 5 are grouped together...
