    we have 12+0=12 12 is the same as 12 does that sound like an identity or associative property?

    and I meant to say 12+0 is the same as 12* associative property we are changing where the grouping symbols are

    The identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself.

    hint: that operation definitely isn't multiplication

    I know it's not multiplication. You are explaining step 2 (5 + 5) + (12 + 0) The question is about Step 3

    yes!!! The identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." This is equivalent to saying a+0=a The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself. a*1=a
