On Sunday, September 4th, the soldiers were very polite. O Weather: If you put an inconspicuous decimal point in the middle of "123", it will become "1.23" or "12.3". If you also put an inconspicuous decimal point in "456", it will become "4.56" or "4.56". Unit 7, we learned the multiplication and division of decimals, which made me feel deeply! The first point: When the columns are vertical, the numbers should be aligned. When the column is vertical, many students often mistake integer for integer and decimal for decimal. If you do that, it would be a big mistake! The correct method should be this: No matter where the decimal point is, when the column is vertical, the ends of the two numbers must be aligned. Only the results and answers calculated in this way are correct! The second point: Never point the decimal point in the process of vertical arrangement. This is a common problem of many students. The decimal point of the exam will be deducted, and you will regret it! Number three: Be careful. Multiply a decimal by 10, 100, 1000 ... or divide a decimal by 10, 100, 1000 ... Never make a mistake about the position and direction of the decimal point! Let's study math seriously! There are still many secrets waiting for us to explore in the kingdom of decimals! I wish you a happy Mid-Autumn Festival! Smile. I wish I could help you. ╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥╥957 In today's math class, we learned the multiplication of decimals. The humorous and vivid explanation of the math teacher really benefited us a lot!

I used to be used to multiplication without decimal point, so I felt very fresh and curious when I came into contact with decimal multiplication, and immediately brought interest in learning! However, it is precisely because I am used to integer multiplication that I always misplace the decimal point, but I am not discouraged, and the teacher has not abandoned me, but patiently explained it to me again and again! Finally, through the teacher's teaching and my efforts, I finally understood thoroughly!
