+# Representing data
+
+Probably before grade school, you learned to count from 1 to 10 on your fingers.
+Just like you, the _decimal_ number system gets its name from the ten digits it
+has to work with.
+
+In mathematics, we typically count from 0 to 9 and then increment the next digit
+up and start counting over again at 10.
+
+The _decimal_ system is also called _base 10_ for this reason.
