The solution to the problem is one of the more distinctive elements of this set of textbooks. Prior to the revision of the textbooks, the strategy for problem solving was arranged on an individual basis from the second semester, which included listing, drawing, enumerating, retiring, replacing, assumptions, and conversions. The revised textbook of this part of the content of the appropriate adjustments and enrichment: First, drastically reduced the difficulty of examples and exercises, to further emphasize that students understand the mathematical thinking and solving the problem in the process of thinking; the second is to increase with the conditions from Thinking or thinking from the problem to solve the problem of thinking about the content of the strategy, highlighting the basic methods and steps to solve the problem, strengthening the strategic choice and comprehensive use of the third is to
