6. Draw a light blue pattern under the handwritten newspaper. Draw a ruler with light blue and blue strokes and put it in the middle of the hexagon. Draw horizontal lines in hexagonal and triangular rulers with rose red and blue.

The history of mathematics shows that the emergence and development of important mathematical concepts play an inestimable role in the development of mathematics. Some important mathematical concepts play a fundamental role in the emergence of mathematical branches. The function we just learned is a very important concept. Since Descartes introduced variables, concepts such as variables and functions have increasingly penetrated into various fields of science and technology.
