大家都知道,“0”是一个再简单不过的数了,连幼儿园的小朋友都会写、会读.然而就是这个不起眼的数字,有时在解题中却起了大作用,忽略它的存在,你就要付出惨重的代价,一不留神,你就会陷进出题者布下的陷阱,无法自拔.鉴于此,本人把学生在做题时由于不考虑“0”而出现的错误列举出来,分析原因并给出正确解答过程,以便在以后的解题中,学生再遇到类似的题,能尽量不出错或少出错,从而提高解题的正确率. As we all know, “0 ” is a simple number, even kindergarten children will write and read. However, this humble number sometimes has a great effect in solving problems and ignoring it You have to pay a heavy price, an inattentive, you will fall into the trap of the subject, unable to extricate themselves. In view of this, I put the students in the problem because they do not consider “0 ” error Listed out, analyze the reason and give the correct answer process, so that in the future problem solving, students encounter similar problems, try to make no mistakes or less mistakes, so as to improve the correctness of the problem-solving.
