How do you calculate 2 05x1 41 vertical calculation?

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: 1 205=205

Step 2: 4 205=8200

Step 3: 1 205=20500

According to the above calculation steps, the combination result is moved to the left by 4 decimal places for the check

Extended information "Calculation": The divisor is calculated from the high position of each digit of the divisor, the quotient obtained from each calculation is retained, and the remainder is added to the next digit for calculation, and the number of digits of the dividend 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: 289 141=2 The remainder is: 7Step 2: 70 141=0 The remainder is 70

Step 3: 705 141=5 The remainder is: 0

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

To calculate in an easy way:

The most common method used in simple calculations is the multiplicative distributive property. The multiplicative distributive property refers to ax(b+c) = axb+axc, where a, b, c are arbitrary real numbers.

Conversely, AXB+AXC=AX(B+C) is called the inverse of the multiplicative distributive law (also known as extracting the common divisor), especially when a and b complement each other, this method is more useful.

There are also times when the associative property of addition is used, such as a+b+c, where b and c are complements to each other, so you can combine b and c and multiply it with a.

Multiplication Properties:

1. Multiply the product of several numbers by a number, so that any factor in the product can be multiplied by this number, and then multiplied by other numbers.

2. Multiply the difference between two numbers and one number, so that the subtracted number and the subtracted number can be multiplied by this number respectively, and then the resulting product can be subtracted.

Hello, this is a multiplication problem with multiple decimal places.

Pay attention to the position of the decimal point during the problem solving.

The solution idea is as follows:

Happy learning, thank you**

<> first do it according to the whole number of the bureau, and finally look at the decimal number of points.

Please see the picture below for the vertical type.

Hope it helps.

If satisfied. Thank you.

Actually, the method of decimal calculation is the same as that of integer calculation, and in the process of calculation, we can align the digits and then point out the decimal point at the end.

How do you calculate it vertically?

Hopefully, thank you

Summary. Vertical calculations?

The above is the calculation process, I hope it can help you.

Summary. The group is divided by a factor of 100.

Vertical calculations. The group is divided by a factor of 100.

So the answer is 286

I hope it helps, if there are no other questions, can you give a like, thank you very much.

This is a multiplication calculation problem that involves the decimal part, so according to the requirements of the Nachun problem, the vertical calculation method is as follows.

Therefore, in mathematical calculations, mastering the correct calculation methods and rules is the most important point, and we should also pay attention to the resistance of the hall and do more practice problems.

Because 27 15 = 27 (10 + 5) using the nuclear oak and changing the multiplication method such as the spine method of the distributive law is 27 10 + 27 5 = 405, plus the decimal point is.
