在去年中專校代数初出版时,讀了“近似計算”一章,曾写几点意見,投登本刊(56年11月号)。再讀新出版的中專校数学教科書——几何、三角、高等数学,觉得各教科書在貫徹近似计算方面,基本上已完成了中專校数学教学大綱所提出有关的教学任务,但在具体問題上,我想再提出几点意見,請同志們指正。 At the beginning of last year’s algebra at the secondary school, the chapter “Approximate Calculations” was read. Several opinions were written and posted in this issue (November, 56). After reading newly published textbooks on mathematics in secondary school-Geometry, Triangle, and higher mathematics, I feel that textbooks have basically completed the teaching tasks proposed in the mathematics syllabus of secondary school schools in carrying out approximate calculations, but the specific issues In the past, I would like to make a few more comments. Please ask the comrades to correct me.
