初中数学课本中出现过一些数和点的集合,如:自然数的集合、有理数的集合、不等式解的集合等,但学生并不清楚“集合”在数学中的含义,只是对集合有了初步的印象。事实上,研究集合的数学理论在现代数学中被称为集合论,在数学中占据着独特的地位,其基本概念已经渗透到数学的所有领域。如果把现代数学比做一座无比辉煌的大厦,那么可以说集合论正是构成这座大厦的基石,由此可见它在数学中的重要性。“集合”是中职数学中接触最早的数学概念之
There are some sets of numbers and points in the textbook of junior high school, such as natural number set, rational number set and inequality solution set, but the students do not know the meaning of “set ” in mathematics, Preliminary impression. In fact, the mathematical theory of research collection is called set theory in modern mathematics, occupying a unique position in mathematics, and its basic concepts have penetrated into all fields of mathematics. If we compare modern mathematics to a majestic mansion, it can be said that anthropomorphism is the cornerstone of the building. It shows the importance of math in mathematics. “Set ” is the earliest math concept in vocational mathematics
