First, master the basic rules of arithmetic. Mastering the basic rules of arithmetic, including the rules and order of addition, subtraction, multiplication, and division, as well as some commonly used calculation techniques such as rounding and grouping, is the foundation for performing quick mental arithmetic. Only by mastering these basic rules can we lay a solid foundation for improving our mental arithmetic skills. Second, practice often to improve proficiency. Practice is the key to improving mental arithmetic skills. Through extensive practice, we can increase our sensitivity to numbers and familiarity with arithmetic rules, thereby improving the speed and accuracy of our mental calculations. It is recommended to set aside some time every day for mental arithmetic practice, starting with simple problems and gradually increasing the difficulty. Third, use mental calculation techniques. Mental calculation is the key to improving the speed of mental arithmetic. In the process of mental calculation, we can use some techniques to help us quickly obtain the answer. For example, we can use the memory palace method to associate numbers with familiar locations or objects, thereby helping us remember and calculate; or we can use some simple algorithms, such as multiplication tables. Fourth, pay attention to the characteristics of the problem. When performing mental arithmetic, pay attention to the characteristics of the problem. Some problems have obvious patterns and characteristics that can be discovered through observation, which can simplify the calculation process and quickly obtain the answer. For example, for problems with periodic laws, we can use the periodic law to simplify the calculation process. Fifth, maintain a calm attitude. When performing mental arithmetic, maintain a calm attitude and avoid calculation errors caused by nervousness. You can use deep breathing, relaxation techniques, etc., to alleviate nervousness. At the same time, believe in your ability to complete the mental arithmetic task and maintain self-confidence and patience.
