-7+[(8⋅m)⋅18]+7
Using the Commutative Property of Addition, we can rearrange the equation:
-7+7+[(8⋅m)⋅18]
Simplifying the middle terms using the Inverse Property of Addition (-7+7=0):
0+[(8⋅m)⋅18]
Simplifying the equation further using the Identity Property of Addition (0+a=a):
[(8⋅m)⋅18]
Using the Associative Property of Multiplication, we can rearrange the equation:
(8⋅18)⋅m
Simplifying (8⋅18=144):
144⋅m
Simplifying further using the Inverse Property of Multiplication (a/1=a):
(144⋅1/8)⋅m
Simplifying (144⋅1/8=18):
18⋅m
Finally, using the Identity Property of Multiplication (a⋅1=a):
m
