Counting fingers or toes or even words in a paragraph can be done routinely by most adults. This lesson, covering pages 84 to 90, will introduce you to notation and techniques which will considerably extend your ability to count all kinds of things, some of which you will encounter later in this course, some will come up sometime in your life outside of class, and some might be interesting if you give them a fighting chance.
