Chapter 1 - Section 1.6 - Multiplying and Dividing Real Numbers - Exercise Set: 136

Answer

Because the numbers are the same, the answer will not change. By the commutative law, we know that just because the order of the numbers changes, that does not mean that the answer will. For example, $2\times3$=6 and $3\times2$=6. The order changed but you get the same result

Work Step by Step

If a and b are any real numbers, is the statement a * b = b * a always true? Why or why not? Use prior knowledge about laws to state that the commutative property make a*b=b*a
