Recall that we are given the numbers 2*7 and 7*2. By a fact, we have that


7\cdot2\text{ =2}\cdot7

Note that in both cases, we are multiplying numbers 2 and 7, but what is changed it the order in which we do so. On the expression on the left we are multiplying 7 times 2, and on the expression on the expression on the right we are multiplying 2 times 7. This two expressions are equal due to the conmutative property of the multiplication of integers.
