Comprehension of elementary mathematics compulsory primary school mathematics 0 includes three parts: ① knowing 0; ② subtracting 0; ③ adding 0 to 0. According to the teaching practice, we think that these three parts, We should know the number of 0, to clarify its significance as the emphasis on the addition and subtraction of 0 is based on the significance of the number 0, at the same time, the meaning of 0 has great impact on students to further study mathematics. This important point allows students to understand the significance of the number of 0 from the following aspects of teaching.
