In Lessons 1 through 4 we have discussed powers of numbers, and we have seen how numbers can be expressed as multiples of powers of numbers. In the next lessons we are going to use this new knowledge about numbers and powers to develop a number system that uses only eight symbols to do the work of ten.
DON’T GO ON TO LESSON 5 if you’re at all confused about the material that’s been covered so far. The eaiest way to review is to reread the summaries at the conclusion of each lesson and to work the Self-Test Questions again. The summary of Lesson 1 begins on Page 38. The summary of Lesson 2 begins on Page 89. The summary of Lesson 3 begins on Page 121.
Lesson 5 begins on Page 154.
