−7+ ? +[(8⋅m)⋅18] Commutative Property of Addition

Question

? +[(8⋅m)⋅1/8] Inverse Property of Addition

Answer 1

-7 + ? +[(8⋅m)⋅18] + ? +[(8⋅m)⋅1/8]

Using the commutative property of addition, we can rearrange the terms to simplify the expression:

-7 + ? + ? +[(8⋅m)⋅18] +[(8⋅m)⋅1/8]

Now, using the inverse property of addition, we can find the value that needs to be added to -7 to get a sum of 0:

-7 + 7 + ? + ? +[(8⋅m)⋅18] +[(8⋅m)⋅1/8]

Therefore, the missing value is 7.
