Problems solved by technology

[0003] However, the existing applications for solving mathematical problems generally only output the correct answer. For the reasoning path, especially the calculation process of more complex problems, such as "(3-3x) / (3x-1)=3 / (6x-2)", It is difficult to show clear, reliable, and accurate reasoning steps, and even some math problem answering applications have difficulty outputting correct answers to complex problems, which makes users' needs unsatisfactory
[0004] It is precisely because the existing technology does not express the intention of the question itself and the reasoning process of solving the question when answering the question, but only outputs the result of the question; and by searching the massive question bank to give the answer, the user learns from the answer It can only understand relatively superficial knowledge, but cannot deeply understand the various changes of the topic and the corresponding problem-solving ideas. Therefore, the existing automatic problem-solving technology will affect the user's problem-solving vision to a certain extent, which is not conducive to improving learning Efficiency, unable to achieve the purpose of imparting knowledge in the true sense

specific Embodiment approach 2

[0061]Specific implementation mode 2: The pre-built knowledge rule base can be based on the collected real answer data, from which the personalized problem-solving habits can be summarized, and problem-solving skills can be extracted, which can be used to apply knowledge other than basic knowledge to current math problems Since the real answer data is huge and can be updated regularly, it can cover one or more problem-solving methods, so that the mathematical problems to be solved, the step-by-step answer process, and the obtained answers can be connected into one Or multiple problem-solving paths; the starting point of the problem-solving path is the math problem to be solved, the end point is the final answer, and the nodes in the middle are composed of step-by-step solution results.

specific Embodiment approach 3

[0062] Specific implementation mode 3: Summarize the basic knowledge of mathematics and individual problem-solving skills to form a global rule model, and through independent learning, the knowledge rule base can be continuously expanded and updated, so that under the condition of ensuring correct results, due to the aforementioned two Therefore, it can give a more reasonable and wider coverage solution path for mathematical problems.

[0063] Based on the above "implementation mode three", taking the relatively simple junior high school teaching as an example, firstly, based on the basic knowledge points of junior high school mathematics principles, such as: addition, subtraction, parentheses, distributive laws, etc., the basic rules for solving problems can be constructed; and then through Automatically learn various problem-solving thinking skills that students use in each knowledge point, such as "3*2+4*2", students apply the reverse problem-solving skills of multiplication...

Abstract

The invention discloses a mathematical problem answering method and device, and the method comprises the steps: generating one or more problem solving paths of a mathematical problem to be solved according to the mathematical problem to be solved and a pre-constructed knowledge rule library; wherein the question-solving path represents that the mathematical question to be solved is reasoned step by step until a complete question-solving process of a final answer is solved; and outputting one or more question-solving paths. Through the mathematical problem answering method provided by the invention, the user can experience the application skills of the knowledge points from the problem solving path, so that the understanding degree of knowledge and the learning efficiency are improved.

Description

technical field [0001] The invention relates to the field of intelligent education, in particular to a method and device for solving math problems. Background technique [0002] With the continuous development of automatic answering technology for math questions, users can record math questions by taking pictures or searching questions, for example, by taking pictures. The information is searched through the massive question database to find the most relevant question and output its answer. If the question is not found or if the searched question has no answer, the answer cannot be obtained. [0003] However, the existing applications for solving mathematical problems generally only output the correct answer. For the reasoning path, especially the calculation process of more complex problems, such as "(3-3x) / (3x-1)=3 / (6x-2)", It is difficult to show clear, reliable, and accurate reasoning steps, and even some math problem answering applications have difficulty outputting co...
