−7+[(8⋅m)⋅1/8]+7
Apply the Commutative Property of Addition:
= -7 + 7 + [(8⋅m)⋅1/8]
Apply the Inverse Property of Addition:
= 0 + [(8⋅m)⋅1/8]
Apply the Identity Property of Addition:
= [(8⋅m)⋅1/8]
Apply the Associative Property of Multiplication:
= (8⋅m)⋅(1/8)
Apply the Inverse Property of Multiplication:
= (8⋅m)⋅(1/8)
Apply the Identity Property of Multiplication:
= m
Therefore, −7+[(8⋅m)⋅1/8]+7 is equivalent to m.
