Cleverly using the incremental method to solve the problem analysis of Jiangsu Sheyang High School Qian Junxian for two real numbers a and b, if a>b, then we can make a=b ten t, where t>0 is called increment, through the increase The method of solving and solving problems by using incremental substitutions for quantity elements is called incremental method. The incremental method is an important way of thinking. It has a very wide range of applications in middle school mathematics. Many complicated mathematics ask...
