Abstract: Mathematics, like other natural sciences, has its unique aesthetic characteristics. Mathematical beauty, whose basic forms are simplicity, symmetry, unity, harmony, singularity and thinking, is often expressed by symbols, formulas, theories, structures, methods and applications of mathematics. If teachers can adopt mathematical beauty to cultivate students' aesthetic ability and make students fully feel and appreciate the mathematical beauty in teaching, it can help stimulate students' interest in learning, enlighten their thinking and develop their creativity.
