QUESTION 2
Which of the following shows the Commutative Property of Multiplication?(1 point)
Responses
a×(−1)=−a
a times left parenthesis negative 1 right parenthesis equals negative a
a×(b×c)=(a×b)×c
a times left parenthesis b times c right parenthesis equals left parenthesis a times b right parenthesis times c
a×1=a
a times 1 equals a
a×b=b×a
