Chapter 1 "Rational Numbers" 1. The concept of rational numbers includes the meanings of positive and negative numbers, the classification of rational numbers, the number axis, the opposite number, the absolute value and the reciprocal. 2. The operations of rational numbers include addition, subtraction, multiplication, division, multiplication and their mixed operations. This is the focus and difficulty of this chapter. 3. Scientific counting method, divisor and average significant number.

The second chapter is Algebraic Expression 1. The concept of algebraic expression includes the definitions of monomial, polynomial and algebraic expression, the coefficient and degree of monomial, and the degree and term of polynomial. Similar items 2, using letters to represent numbers 3, merging similar items, removing brackets and simplifying evaluation are the key and difficult points in this chapter.

Chapter 3 "One-dimensional linear equation" 1, the concept of one-dimensional linear equation, and the solution of one-dimensional linear equation will be tested. 2, the nature of the equation 3, the solution of the unary linear equation (denominator, brackets, shift terms, merging similar terms, coefficient into 1)4, the column equation to solve the application problem This is the focus and difficulty of this chapter.

Chapter 4 "Preliminary Understanding of Graphics" 1. Understand several special three-dimensional figures, expand the side of the three-dimensional figure from different directions, and form a whole geometric figure. 2. Comparison of straight line, ray and line segment, midpoint of line segment, size of line segment, sum and difference of line segment, application of two axioms (two points determine a straight line, and the line segment between two points is the shortest). 3. Two concepts and expressions of angle, comparison of angle, definition of angle bisector, and operation between degrees, minutes and seconds. 4. The concepts of complementary and angle-dependent operations. 5 Simple application of two theorems (same complementary angle is equal, complementary angle is equal)
