1.数的整除性所研究的对象是什么?大家知道,小学数学研究的主要对象是整数,而数的整除性则是研究整数性质的基础。所以,“数的整除性”一章是每个小学数学教师必须牢固掌握的基本知识之一。这一内容主要介绍了约数与倍数、公约数与公倍数、最大公约数与最小公倍数等概念以及它们的求法;数的整除性质以及数的整除特征。其中最大公约数与最小公倍数是本章的重点,数的整除性质是整除特征的理论依据。2.“整除”与“除尽”是一回事吗?“整除”和“除尽”是两个不同的概念。
1. What is the object of the divisibility of the numbers? As we all know, the primary object of elementary mathematics research is the integer, and the divisibility of numbers is the basis for the study of the properties of integers. So the chapter “Divisibility of Numbers” is one of the basics that every primary school mathematics teacher must firmly grasp. This section mainly introduces the concepts of divisor and multiple, common divisor and common multiple, the greatest common divisor and the least common multiple, and their solutions; the divisibility of numbers and the divisibility of numbers. The most common divisor and the least common multiple are the focuses of this chapter. The integer divisibility of numbers is the theoretical basis of divisibility. Is Divisibility and Divisibility the same thing? Divisibility and Divisibility are two different concepts.
