Suppose we have a formula: 3×(2+4), which means three times the sum of two numbers in brackets. Specifically, this formula can be expressed as: first, calculate the sum of the numbers 2 and 4 in brackets to get 6, and then multiply it by 3 to get 18.

If you want to use graphics to express the meaning of this formula, you can consider using some graphics or symbols to represent numbers and operation symbols. For example, we can draw three small circles for the number 3, then two small circles for the number 2, and finally four small circles for the number 4. These small circles can be combined into a larger circle, which represents the calculation result of this formula.

In addition, we can use some symbols to simplify the calculation process. For example, we can use the arrow symbol to represent multiplication, and use the arrow to connect three small circles and two small circles to represent the meaning of 3 times 2. Similarly, we can also use other symbols to represent operations such as addition and subtraction.

The formula explains the advantages of graphic method;

1, intuitive understanding: the graphic method can present the formula intuitively, helping students to better understand the meaning of the formula and the calculation process. Compared with abstract numbers and operation symbols, graphics have more intuitive visual effects, which can better attract students' attention and improve their interest in learning.

2. Simplify calculation: Graphic method can simplify the complicated calculation process into simple graphic combination and calculation, and improve the calculation speed and accuracy of students. For example, by converting numbers into graphs, students can understand the quantitative relationship and calculation process more intuitively, and thus get the correct answer more easily.

3. Improve mathematics literacy: Graphic method can not only help students master basic mathematics knowledge, but also cultivate students' mathematical thinking and problem-solving ability. By linking mathematical problems with graphics, students can better understand the essence of problems and solutions, so as to better use what they have learned when solving practical problems.
