How do you write 15 6x15 vertical calculation?

Vertical calculation results 156 15 (

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: 5 156=780

Step 2: 1 156 = 1560

Based on the above calculations, the sum is 2340, and since the multiplier is expanded by a total of 10 times, the product is 234

Check: 234 15=

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: Step 1: 23 15=1 The remainder is: 8Step 2: 84 15=5 The remainder is: 9

Step 3: 90 15=6 The remainder is: 0

According to the above calculation steps, the combined result is:

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

<> is equal to 234, first multiply 156 by 5, and then multiply 156 by 1 to get the number added, since there is a decimal point, the added number should also be added to a decimal point.

How do you write the vertical calculation that this teacher should have taught? It's to write it on it. 15, written below a flavor alignment. Then write Cheng Hao on the left side of 15. Write a horizontal line underneath. Then multiply them one by one.

In the column-vertical process, we can use short division.

<> vertical counting bridge calculation** as shown in the picture above, there is no dry Qi Pei.

Direct division operation on the line, 15 divided by 5 is equal to three, the integer part is early skin 3, and then 2 can not be divided, Heng Qingqing on 0, and then 25 divided by 5 equals 5, so the final equal.

According to the title:

Calculate it directly, and the final result is.

Vertical calculations:

Divide the divisor by the high digit of the dividend to see the first 2 digits of the dividend.

of vertical copy

Calculation: Expand the divisor by 1000 times, remove the decimal point to make it a whole number.

The dividend is also expanded by a factor of 1,000 at the same time.

The vertical pure state Huai formula calculation is shown in the figure below.

Calculated vertically. The method of calculating the decimal trace grasp division and integer division is the same, and the divisor is written on the inside of the division sign by Zi Tongqing, and the divisor is written on the outside of the nickname. It is important to note that the decimal point of the quotient should be aligned with the decimal point of the wheel or the dividend.

The vertical is as follows:

Analysis: Before calculating, the expansion of 100 times becomes 156, 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 the end of the number will be aligned with which of the second factor of the closed bucket is aligned with which of the second factor of the closed bucket is aligned with which of the second factor of the second factor.

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

As a result, the vertical calculation and correction process of the slag body is shown in the following figure.

The calculation of the missing guess vertical large closure is as follows:

Then this circle belongs to multiplication operation, and we can get the answer by the multiplication and holding first method of vertical calculation.
