审题是解题的基本前提,审题时细心谨慎,准确得当,对正确解题有很大的帮助;反之,审题时马虎大意,过于草率,解题时就会差之毫厘、失之千里,进而导致失分.因此,在解答数学题时,审题一定要仔细谨慎,抓住题目主旨,明确条件要求,准确理解题意,找准解题的突破口和切入点,从而有效解题.一、挖掘隐含条件,还其庐山真面目隐含条件是指题目中那些不易被察觉、若隐若现、未明确表达出来却又客观存在的已知条件.在初中数学题中,有许多基础常规
Moderation is the basic prerequisite for problem solving, careful examination carefully, accurately and properly, the correct solution to a great deal of help; the other hand, when deliberation slash carelessly, too sloppy, the problem will be the slightest difference, lost thousands of miles, thus Leading to lost points.Therefore, in the solution of math problems, the trial should be carefully careful examination, to grasp the subject of the key to clear the conditions and requirements, accurate understanding of the problem, find the breakthrough point and entry point, thus effectively solving problems. Implicit conditions, but also the true meaning of the Lushan is the hidden conditions that are not easily detected in the title, looming, but not clearly expressed but objectively known conditions in the junior high school math problems, there are many basic rules
