Responses
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×b=b×a
a times b equals b times a
a×(−1)=−a
a times left parenthesis negative 1 right parenthesis equals negative a
a×1=a
The correct response is "a×b=b×a." This equation shows the commutative property of multiplication, which states that the order of the factors does not affect the product. Both sides of the equation yield the same result when multiplied.
