在中小学数学教学、培训以及研修学习中,不少教师都提到中国数学史的正负数的问题,笔者对此很有兴趣,也感到此内容十分重要,但有关这方面的介绍也不尽相同,这给我们的数学教学与研究带有一定的不便.因此,本文在查阅相关文献的基础上,给出一些数学史料,使大家对此有一个更清楚、更准确的认识.同时,也提出一点自己的认识和理解,希望与同行作更进一步的交流,也权当对数学史学习与应用的一点体会.1关于中国数学史中的正负数中国是世界上最早引入负数并给出正负数运算法则的国家.可是究竟应当怎样认识正负数,却需要搞清
In the teaching of primary and secondary mathematics, training and training, many teachers have mentioned the issue of the number of positive and negative Chinese math history, I am very interested, but also feel this content is very important, but the introduction of this area nor Do the same, which gives our math teaching and research with some inconvenience.Therefore, this article on the basis of access to relevant literature, gives some mathematical history, so that everyone has a clearer and more accurate understanding of this.Meanwhile, Also put forward some of my own understanding and understanding, hoping to further exchanges with their peers, but also when the history of mathematics should learn and apply a little experience.1 Positive and negative numbers in the history of Chinese mathematics China is the world’s first to introduce negative and give The positive and negative algorithm countries. However, how to recognize positive and negative numbers, but need to find out
