0 How to 4x15 column vertical?

Vertical process analysis.

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: 5 4=20

Step 2: 1 4=40

According to the above calculation steps, the combination result is moved to the left by 1 decimal place, and the product is 6, and the calculation: 6

Check Extended Data: 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 4, and the dividend is expanded by the same multiple as 60

Step 2: 6 4=1 The remainder is: 2

Step 3: 20 4=5

According to the above calculations, the result quotient of the combination result is 15

<> vertical calculations** as shown above.

Column vertical fifteen times 0.4, you just write 15 on the top and 0.4 on the bottom, four on five, 0 on one.

This is a simple multiplication problem, and the result is equal to 6.

The vertical is as follows:

Analysis: Before calculating, the expansion of 100 times becomes 32, and the expansion of 100 times becomes 15, and then the calculation is performed according to the multiplication of integers.

From the right, multiply the first factor by the number on each of the second factor, and multiply it by which digit of the closed solution, and the end of the number will be aligned with which digit of the second factor is aligned with which digit of the second factor.

After calculating the product, and then see how many decimal places there are in the multiplier, count the number of decimal places from the right side of the sedimentary state, and point to the decimal point. (In decimal calculation, the 0 at the end of the decimal part of the product is removed).

The calculation of the vertical closure of the multiplicative permeability state such as the bundle is as follows:

The vertical settlement is as follows:

Analysis: First remove the decimal in the factor, expand it by 1000 times to 82; I enlarge it 100 times and become 41. The calculation is then carried out according to the method of integer multiplication.

82×1＝82；82×40＝3280。Then add 82 and 3280 to get 3362. There are five decimal places in the last observed factor, so counting the decimal points from the right side of 3362 to the left gives the correct product.

As shown below:

Multiply, first as 82 times 14, 82 multiplied by 4 and 10 respectively, and then add the respective results to equal 1148, the multiplier has a total of five decimal places, then the final answer is.

Vertical parsing steps.

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 82=328

Step 2: 1 82 = 820

According to the above calculation steps, the combination result is moved to the left by 5 decimal places.

Extended data for checking: the divisor is calculated from each digit from the high position to the divisor, the quotient obtained from each calculation is retained, and the remainder is added to the next digit for the calculation, and the divisor is calculated in this order, and the quotient obtained is combined in order, and the remainder is the result of the last operation.

Problem solving: Step 1: 114 14=8 The remainder is: 2

Step 2: 28 14=2 The remainder is: 0

According to the above calculation steps, the result of the combination is quotient.

<> check: 72 times 5 equals 360, 72 times 1 equals 72, 360 plus 72 equals 1080, move back 5 digits, so.

The knot mask is suspicious of the fruit type.

The vertical calculation posture is as pure as the book of honor: bright and empty.

Vertical parsing steps.

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

Problem solving: Step 1: 4 82=328

Step 2: 1 82 = 820

According to the above calculation steps, the combination result is moved to the left by 5 decimal places.

Extended data of the check: the dividend from the high position of the change of each digit for the divisor operation, each time the calculated quotient is retained, the remainder is added to the next single digit for the calculation, and then the divisor is calculated in the order of the number of digits, and the obtained quotient is combined in order, and the remainder is the result of the last operation.

Problem solving process: Step 1: 114 14=8 The remainder is: 2Step 2: 28 14=2 The remainder is: 0

According to the above calculation steps, the result of the combination is quotient.

1. Idiomatic writing: the dividend - the divisor (one horizontal and one skimming) - the divisor - the quotient - the lapin - the product - the hidden - the remainder of the reed branch.

The method of vertical columns is as follows: each column of Hongranhui needs to be separated by a horizontal line. 56 070 70 0
