Concept explainers
Explain in your own words why we compare numbers in the base-ten system by starting at the left-most place at which there is a nonzero digit and then proceeding to the right if necessary. For example, we compare 234 and 219 by starting at the hundreds place and then moving to the tens place. We compare 1122 and 987 by starting at the thousands place. What is it about the base-ten system that allow us to compare numbers this way?
