One-Dimensional Linear Equations Talk About Turning Face

Abstract

Classmates, have you ever heard of such an old question? "Looking at the seventh floor of the towering tower from afar, the red lights have doubled, with a total of 381 lights. Try to calculate the number of lights on the top of the tower." Can you solve the answer? What method do you use? Through the study of this chapter, you will master a new problem-solving method-column equations, you will find that a complex problem will become very simple, the idea of equations is a very Broad way of thinking.
