3 4 9 9: (3 (9-4))+9)=24**The general process starts from finding the problem and asking the question, and after discovering the problem, make assumptions about the answer to the problem based on their own knowledge and life experience Design the first plan, including the selection of materials, design methods and steps, etc. According to the **plan**, get the results, and then analyze whether the results are consistent with the assumptions, so as to draw conclusions Not all problems get the right conclusion at one time Sometimes, due to** The method is not perfect and can also lead to wrong conclusions Therefore, after reaching the conclusion, it is also necessary to reflect on the whole process of the general methodological steps of the experiment: asking questions, making hypotheses, making plans, implementing plans, drawing conclusions, expressing and communicating

The most commonly used methods in science are observation.

Experimental methods, survey methods, data analysis methods, etc

Observation is a basic method of science** Scientific observation can be made directly with the naked eye or with the help of a magnifying glass.

Instruments such as microscopes, or the use of cameras, video recorders, video cameras, and other tools, sometimes it is also necessary to measure scientific observations with a clear purpose; Observations should be comprehensive, meticulous, and realistic, and recorded in a timely manner; Be planned and patient; Think positively and record in a timely manner; To exchange views and discuss the design of the experimental protocol should be carried out closely around the questions and hypotheses raised When studying the effect of one condition on the subject of the study, the experiment carried out under the same conditions except for the different conditions is called a control experiment.

General steps: identify and ask questions; gather information related to the issue; make assumptions; design of experimental protocols; Conduct experiments and record them; analysis of experimental phenomena; Conclusion Investigation is one of the common methods of science When investigating, we must first clarify the purpose of the investigation and the object of the investigation, and formulate a reasonable investigation plan During the investigation process, sometimes because the scope of the investigation is very large, it is necessary to select a part of the survey objects as samples During the investigation process, it is necessary to record truthfully The results of the investigation should be sorted out and analyzed, and sometimes the statistical methods should be used to collect and analyze data is also one of the common methods of science There are many ways to collect information Go to the library to consult books and newspapers, and visit relevant people, The form of information includes text, data, and audio-visual data, etc., and the information obtained should be sorted out and analyzed, and answers and clues should be found from it.

Draw any 4 cards (called a deck) and count the number on the board as 24 with addition, subtraction, multiplication, and division (parentheses, and advanced players can also use multiplication and factorial operations). Each card must be used and can only be used once. If the card drawn is , then the equation is (9-8) 8 3=24.
