去年六月,华罗庚等同志到上海讲授和推广数学中的“统筹方法”和“优选法”。上海市的同志遵照伟大领袖毛主席“理论和实际统一”,知识分子“同工农兵结合”的教导,安排他们先到上海炼油厂蹲点,一面向工人同志学习,接受工人阶级再教育,一面下车间、工地向工人讲授这两种数学方法。在取得典型经验的基础上,又举办了全市性的经验交流会 In June last year, Hua and other comrades went to Shanghai to teach and promote “co-ordination methods” and “law of preference” in mathematics. Comrades in Shanghai follow the teachings of Chairman Mao Zedong, the great leader, “theoretically and practically,” and the “combination of work with industry, peasants and soldiers” by the great leaders of Shanghai Municipality, and arrange them to go to the refinery in Shanghai first to study in the workplace and to accept the reemployment of the working class Workshop, site workers to teach these two mathematical methods. On the basis of obtaining typical experience, we held a city-wide experience exchange meeting
