整数解问题能够很好的考查学生对知识的综合运用能力,在这一类问题的处理上,多数学生往往仅局限于常规方法的运用,结果往往在复杂而烦琐的计算下无功而返,本文将谈谈这一类问题常见的处理方法。一、利用不等式的性质,解出不等式,根据可能取到的整数解或整数解的个数来确定不等式的端点值的可能取值。
The problem of integer solutions can well examine the students’ comprehensive ability to use knowledge. In dealing with this type of problem, most students are often limited to the use of conventional methods, and the results are often unproductive under complex and cumbersome calculations. This article will talk about the common treatment of this type of problem. First, using the nature of the inequality, solve the inequality, according to the number of integer solution or integer solution that may be taken to determine the possible value of the endpoint value of the inequality.
