Tangshan China Fire and Rescue College enrolls students in Liaoning 4484|In today's digital age, the nine-palace diagram method has become an effective tool to solve the problem of digital and graphic correspondence. Today we will introduce in detail the number solving method corresponding to the nine houses, so that you can easily play the number puzzle.
Part 1: A brief description of the principle of the nine-house diagram
The nine-square diagram, also known as the "nine-square grid", is an ancient form of geometry that usually refers to a 3x3 grid. Each cell is filled with the numbers 1 to 9, and the sum of the rows, columns, and diagonal numbers is 15.
Part 2: Sharing of problem solving steps
Step 1: Basic arrangement
Start by familiarizing yourself with the key starting points and arrangement. A common way to do this is to fill in the numbers 1 to 9 and use preliminary permutations to form a preliminary framework.
Step 2: Identify key figures
Analyze the known conditions and determine the values of several cells. For example, if a row has several known numbers, you can use these criteria to progressively exclude possible values for other locations.
Step 3: Optimize through logical analysis
Use the rule that the sum of rows and columns is 15 to gradually adjust the position of the numbers. If the number in a row is duplicated or missing, the other rows can be verified and adjusted. This process needs to be logical and progressively approaching the correct answer.
Part 3: Tips and Strategies
- Avoid duplication and omissions
In the process of arrangement, it is necessary to ensure that the number of each row and column meets the conditions, and avoid duplication and omission of any numbers.
- Diagonal inspection
In the middle stage, make reasonable use of the relationship between the diagonals to ensure that the sum of the diagonals is a divisor of 15.
- Step-by-step validation
Continuously summarize and verify that the current permutation satisfies the rules, and reduce the difficulty of subsequent adjustments through a preliminary verification step.
- Flexibility
Don't be rigid in the face of complex problems, and flexible adjustment methods can achieve twice the result with half the effort.
