An equation containing an equal sign is called an equation. Equations can be divided into contradictory equations and conditional equations. The equation still holds when both sides of the equation add (or subtract) the same algebraic expression, or when both sides of the equation multiply or divide the same algebraic expression that is not zero. The form is to connect two equal numbers (or numbers expressed in letters) with "=".
It is a common game in mathematics to establish equations by moving matchsticks. It takes advantage of the similarity between the numbers typed by matchsticks and Chinese characters, and the movement can change the equation. Such games can make students feel interesting and exercise their thinking at the same time.
