45 0 44, how do you write it vertically?

Arithmetic vertical 45 44

Problem solving ideas: first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier for each number from the last digit in turn, and finally add up the calculated result to be the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiple, and finally the product is reduced by the corresponding multiple;

Problem solving: Step 1: 4 45=180

Step 2: 4 45 = 1800

According to the above calculations, the sum is 1980, and since the multiplier is expanded by a total of 100 times, the product is the check:

Extended Data $ Result of the Validation: The dividend.

The divisor is performed from each digit from the high position, and the quotient obtained each time is retained, and the remainder is retained.

Add the next digit to the operation, and the divisor will be divided into digits in this order, and the obtained quotient will be combined in order, and the remainder is the result of the last operation.

Problem solving process: Step 1: Because the divisor is not an integer, first turn the divisor into an integer of 44, and the dividend is expanded by the same multiple as 1980

Step 2: 198 44=4 The remainder is: 22

Step 3: 220 44=5 The remainder is: 0

According to the above calculation, the calculation step combination result quotient is 45

This is a multiplication problem, and the result is.

Good study habits are the key to achieving good results, in life, to guide children to develop regular preview, review, do exercises, check, correct, compile a set of wrong questions and other good study habits, once the habit is formed, it will have a long-term impact on the future learning path.

to facilitate escrow. Parents and friends should learn to use more supervision instead of discipline, so that children feel that learning is a matter of their own ideas, not forced by parents and schools, so that children will be more motivated to learn.

Communicate with teachers.

Parents should communicate more with teachers, after all, there will be some differences between the child's appearance at home and at school, learn to understand more about the different sides of the child, and keep abreast of the child's learning dynamics, at the same time, to maintain a good relationship with the teacher, try to fight for a better seat for their child and the next table, this should be understood by everyone.

Extracurricular tutoring. If the child feels more difficult to learn, many knowledge points can not be digested in time, and the academic performance has dropped significantly, then it is necessary to find a tutor for the child, preferably a one-to-one professional tutor to help the child solve questions and answer doubts, and digest and absorb the day's homework in time, so that learning can reduce stumbling blocks.

This is a multiplication operation, so we can calculate it through the multiplication operation of vertical calculation, and then we can get the answer is.

Column vertical calculation, pay attention to the position of the decimal point. First of all, you can go on 1Answer: Approximately equal to.

45 The vertical meter is as chaotic as the stove

Summary. You just need to keep two decimal places.

Answer: There is no old 45 vertical dry state calculation method to see the figure with hall 1, first calculate according to the calculation method of integer multiplication. 2. There are several decimal places in the number of factors.

Vertical process operations.

Problem solving idea: the dividend from the high position of each digit of the divisor to the divisor operation, each time the calculated quotient is retained, the remainder is added to the next digit for operation, in this order the dividend is calculated so the digits, the obtained quotient is combined in order, and the remainder is the result of the last operation.

Problem solving process: Step 1: Because the divisor is not an integer, first convert the divisor to an integer of 39, and the dividend is expanded by the same multiple as 1443

Step 2: 144 39=3 The remainder is: 27

Step 3: 273 39=7 The remainder is: 0

According to the above calculation, the result of the combination of the steps of the root bureau is 37

Check: 37

Extended data = > the process of checking: first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier by each digit from the last digit to each digit in turn, and finally add up the calculated result to be the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiple, and finally the product is reduced by the corresponding multiple;

Problem solving: Step 1: 9 37=333

Step 2: 3 37 = 1110

According to the above calculation steps, the result of the combination of reed pie is as follows:
