The 2011 edition of “Primary Mathematics Curriculum Standards” points out that: Everyone learns valuable mathematics and different people get different development in mathematics learning. Error is the inevitable product of learning. Students’ knowledge background, thinking mode, emotional experience and expression form are often different. It is quite normal for them to make various mistakes in their learning process. When “Mathematics ” encounters “Error ”, as long as we think rationally and handle it intelligently, we will find that the mistake of a student is a tremendous wealth in teaching. 1, in the error reason, so that understanding from the fuzzy to clear
