Hello, classmate.

The investigation of mathematical knowledge in comprehensive ability examination mainly includes elementary mathematics, basic knowledge of probability and geometric knowledge. Among them, elementary mathematics accounts for about 60% of the total math score, basic knowledge of probability accounts for about 16% of the total math score, and geometric knowledge accounts for about 24% of the total math score. The examination contents include:

(1) Elementary Mathematics:

The concept, properties, operation and application of real numbers; Algebraic expressions, fractions and their operations; Solution and application of equations (one-dimensional linear equations, one-dimensional quadratic equations, two-dimensional linear equations); Solution and application of inequality (linear inequality in one variable, quadratic inequality in one variable); Arithmetic progression, geometric series.

(2) Basic knowledge of probability:

Permutation and combination; The possibility is preliminary.

(3) Geometry knowledge:

Properties and operations of common plane graphics (triangle, quadrilateral, circle); Plane rectangular coordinate system, equations of straight lines and circles and their positional relationships; Properties and related operations of common three-dimensional graphics (cuboid, cylinder, sphere).
