1. (6 points) There are 172 A's listed below, some of which are organized into groups of ten. As we did in a previous activity, our goal is to organize these A's in a way that corresponds to how we write numbers using the base-ten number system. The organizational system below is a good start, but there is more to do How can we organize them a bit more so that these A's give a clear visual of the meaning of the "1," the "7," and the "2" in the number 172 as single digits in the base-ten system? Show or clearly describe your new organization, and say precisely what each of "1," "7," and "2" represents in your organization.
