1. Preparation materials: paper, crayons, pencils, rulers, scissors, glue, etc.
2. Gently draw a rectangle on the paper with a pencil as the border of the handwritten newspaper.
3. Draw two vertical center lines in the picture frame with a ruler and divide the picture frame into three parts.
4. Write "Equation" with colored pen in the upper left corner, and you can highlight the key points with different colors.
5. You can draw some patterns related to equations in the upper right corner, such as mathematical symbols and equations.
6. You can write something about the definition, properties and solution of the equation in the lower left corner. You can highlight the key points with colored pens.
7. In the lower right corner, you can draw some practical applications related to equations, such as equation applications in physics, chemistry and other fields.
8. Around the whole handwritten newspaper, you can use colored pens or colored paper to cut out some small patterns, such as stars and flowers, to decorate the border.
9. Finally, check whether the contents of the handwritten newspaper are accurate and clear, and whether the typesetting is neat and beautiful.
Origin of the equation
The word equation comes from ancient mathematics, which means equivalence relation in mathematics. As early as ancient Egypt and Mesopotamia, people began to use simple arithmetic equations to solve problems in daily life, such as calculating taxes and exchanging goods.
In ancient China, mathematicians also made important contributions to the study of equations. In mathematical works such as Nine Chapters of Arithmetic, equations are called "Equation Technique" or "Arithmetic Equation" and are widely used to solve various practical problems. These equations are usually solved by moving terms, merging similar terms and solving equations.
With the development of mathematics, the concept and properties of equations are gradually studied in depth. In algebra, an equation is defined as an equation with an unknown number, and the value of the unknown number can make the equation hold. There are more and more kinds of equations, including unary equations, binary equations, higher-order equations, differential equations and so on.
The solution of the equation has been continuously developed and improved. From the initial trial-and-error method to the later algebraic method, trigonometry method and calculus method, mathematicians constantly study and explore new solutions, which make the solution of equations more accurate and efficient.
In the fields of modern science, engineering, economy and society, the application of equations is more and more extensive. For example, in physics, equations are used to describe the laws of motion and interaction of objects; In chemistry, equations are used to describe the process and rate of chemical reactions; In economics, equations are used to describe market supply and demand, price changes and so on.
In a word, equation, as a basic concept and method in mathematics, has been continuously developed and perfected with the development of human civilization, and has made important contributions to human understanding and development.
