无数据计算题的特点是题目中没有明显的用于计算的数据.正是由于这一点,学生面对无数据计算题,往往感到条件不够,无从下手,其实这类题目中都含有一些重要的隐蔽条件,而这些隐蔽条件恰恰是解题的突破口,只要我们认真分析题意,挖掘出题目中的隐蔽条件,问题就会顺利解决. The feature of the no-data calculation problem is that there is no obvious data for calculation in the subject. It is precisely because of this that students face the problem of no data calculation, they often feel that they have insufficient conditions and are unable to start. In fact, these topics contain some important Concealed conditions, and these hidden conditions are precisely the breakthrough point for solving problems. As long as we carefully analyze the meaning of the questions and dig out the hidden conditions in the questions, the problems will be resolved smoothly.
