How to draw the emblem of the Mathematical Science and Technology Festival?

These four quadrants are drawn with different knowledge networks or formulas.

The emblem should highlight the characteristics of thinking and learning. For example, draw a plane rectangular coordinate system or a two-dimensional coordinate system, and pay attention to symmetry. So we can consider the plane rectangular coordinate system. These four quadrants are drawn with different knowledge networks or formulas.

Mathematical science and technology festival tests students' practical ability and logical thinking ability. A series of rich math games are conducive to the improvement of students' mental outlook and competitive consciousness.
