Volume II: Negative Numbers, Cylinders and Cones, Proportion, Statistics and Mathematics Wide Angle.
In the second volume of senior one, students have learned to determine the position of objects according to rows and columns in specific situations. Through the study of position and direction in the second volume of senior four, they further realize that the position of objects can be determined by two conditions in the plane. On this basis, this unit allows students to learn how to use number pairs to represent the position of objects in specific situations or how to use number pairs to determine the position on grid paper, so as to further enhance the existing experience, cultivate the concept of space, and lay the foundation for the third phase of learning "graphics and coordinates".
structure
Many mathematical objects, such as numbers, functions, geometry, etc., reflect the internal structure of continuous operation or the relationships defined therein. Mathematics studies the properties of these structures, for example, number theory studies how integers are represented under arithmetic operations. In addition, things with similar properties often occur in different structures, which makes it possible for a class of structures to describe their state through further abstraction and then axioms. What needs to be studied is to find out the structures that satisfy these axioms among all structures.
