How do you do 18 4 columns? 908 3 How to column

Vertical calculation 180 4

Solution: Divide 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: Step 1: 18 4=4 The remainder is: 2Step 2: 20 4=5 The remainder is: 0

According to the above calculation, the result of the combination of the calculation steps is 45, and the quotient is 45 because the dividend is expanded by a factor of 10.

Calculation: Extended Data - Calculation Results: First align the last digit of the two multipliers, then use the second multiplier respectively, multiply each digit by a multiplier from the last digit, and finally add up the calculated result as the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiplier first, and finally the product is reduced by the corresponding multiple;

Problem solving: Step 1: 5 4=20

Step 2: 4 4 = 160

According to the above calculation steps, the combination result is moved to the left by 1 decimal place, and the product is 18, please ask if you are in doubt, and you are satisfied.

Solution: 18 4 is equal to ( 9 2 ), that is, equal.

It is known how much the demand out of 18 4 is equal to.

Answer: 18 4 is equal to 9 2, [i.e. equal.]

Hello! Negotiate 4, and the remainder is 28

The following figure shows the columnar calculation process.

Hello! Schoolmate.

The quotient is 302 and the remainder is 2

The following figure shows the vertical calculation process.

Please refer to ** Calculation Process, there is a division of remainders.

Hello! Schoolmate.

The following figure shows the vertical calculation process.

Calculated results: 7 out of 51

When the hemp bucket pin is annoying, please and the bucket Zhao, thank you for the empty code!

The 472x9 vertical calculation method is as follows:

472x9=4248

472 9 Vertical Process Analysis.

Reference idea: first Kaihail aligns the last digit of the remainder of the two multipliers, and then uses the second multiplier respectively, multiplies a multiplier for each number from the last digit in turn, and finally adds up the calculated result to the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiplier first, and the final product is reduced by the corresponding multiple;

Problem solving: Step 1: 9 472=4248

According to the above steps, the results are added to 4248

If you have any doubts, please ask and be satisfied.

The 455 40 columns are as follows:

Analysis: The divisor is two decimal places, first look at the first two digits of the dividend, 45 divided by 40 is equal to 1 and 5, and the quotient 1 is written in the ten digits. The remainder 5 and 5 make up 55 divided by 40 equals 0 and 15, and quotient 1 is written in the single digit. 15 is less than 40 as a remainder.

Precautions for division vertical:

1. The whole question should be written in the middle of the writing grid in the workbook, and all the numbers should be of the same size;

2. The numbers to be divided from each other are slightly separated, which is convenient for quotient alignment of digits;

3. The quotient is aligned with the unit digit of the dividend;

4. The product is aligned with the dividend;

5. The remainder is aligned with the unit digit of the dividend.
