最近,在上海数学会主办的“数学英语”班上,我选了一些国外的数学教材作为学员的学习材料。其中相当于我国初中一、二年级程度的《学校数学》(《School Mathematics》)(第二册)和相当于高中程度的《大学代数》(《College Algebra》)两种教材,除了其知识体系上有独到之处以外,在编写方法上也有一定的特色。 Recently, in the “Mathematical English” class organized by the Shanghai Mathematical Society, I selected some foreign mathematics textbooks as learning materials for students. This is equivalent to the “School Mathematics” (Grade 2) and the “College Algebra” equivalent of the high school degree in grades 1 and 2 of junior middle school in China, except for the knowledge system. Apart from its uniqueness, there are also certain characteristics in the method of writing.
