A study of mathematical terms and sentence style to make textbooks more understandable

我们调查了小学生的数学文献，收集了第一个数学句子，难以理解的意义，或容易理解的，等等。通过比较，得出了如何教学生写通俗易懂的句子。我们制定了一个教学大纲，教学生如何避免写难句，并得出了一个原则，使句子易于理解，我们还探讨了逻辑思维和语言表达的关系。

We investigated mathematical literatures for school pupils and collected first mathematical sentences, difficult to get the meaning, or easy for understanding, and others. Comparing them, we obtained how to teach writing sentences easy for understanding. We made a syllabus to teach how to avoid writing sentences difficult to gel the meaning and obtained a principle to make the sentences easy for understanding.We also investigated the relationship between logical thinking and linguistic expression.
