69 99 times 6 88 vertical? How to write

Vertical calculation process.

Reference idea: The multiplication vertical calculation is to convert the multi-digit multiplication into the multiplication of a single digit by the multi-digit result, which is mainly to simplify the multi-digit multiplication and multi-digit calculation, making the calculation more convenient.

Parsing step: Step 1: 8 6999 = 55992 Step 2: 8 6999 = 559920

Step 3: 6 6999 = 4199400

By accumulating each step from top to small, move the product of 4 decimal places to the left for the check

Extended data analysis idea of checking: division vertical calculation from the dividend.

Start the calculation from the high position, if the current digit is not enough to divide, then look at one more place, and divide the remainder of each step.

For the current high position of the dividend and the need to be less than the divisor, the operation process is analyzed

Step 1: 4815 688=6 The remainder is: 687Step 2:

6873 688=9 The remainder is: 681Step 3: 6811 688=9 The remainder is:

619 step four: 6192 688 = 9

According to the above quotient, the combination is 6999

So this can also be done by multiplication of vertical calculations to get the above answer.

Single-digit and single-digit alignment, ten-digit and yes-ten-digit alignment, hundred-digit and hundred-digit alignment.

Then, if you calculate vertically, how to write the dividend should be written in the innermost? Just write it out again.

In fact, it is very simple, we only need a direct calculator, and there is no problem at all.

It's your own step-by-step calculation, are you a fool?

Vertical calculations:Vertically, each number is changed from the previous number; In the vertical column, it is necessary to pay attention to the equal digital alignment; Multiplication is a key focus of primary learning.

Division operations:The dividend expands (shrinks) n times, and the divisor does not change, and the quotient expands (shrinks) n times accordingly. The divisor expands (shrinks) n times, and the dividend remains unchanged, and the quotient shrinks (expands) n times accordingly.

The dividend, divided by two divisors consecutively, is equal to the product of the two divisors. Sometimes simple operations can be performed depending on the nature of division.

For example: 300 25 4 = 300 (25 4) = 300 100 = 3.

Summary. 49 How to use vertical calculation.

Hello, I'm happy to answer your questions, this question is answered by Mr. Xiaotian for your pants, Mr. Xiaotian has ten years of work and pure experience, dedicated to your service, your question I have only repented of seeing, I am sorting out the answer for you, please wait a while, reply to you within a minute, don't worry.

Wait a minute, I'll send it to you on paper.

I'll send it to you on vertical paper. Where is it.

The vertical calculation process of information infiltration under the shirt file:

Therefore, the result of the sliding ridge is:

The decimal point is aligned to the decimal point and the full decimal point is calculated.

Summary. 90-69+8, vertical calculation.

Hurry up. How to column vertically?

This is the answer to this question.

8 is equal to, this is a division math problem, use the division vertical to calculate, the result of the calculation: 8, thank you.

Answer: 8 becomes 800 89. Column vertically first, and then calculate the quotient using vertical. Column Vertical Calculation:

Calculation formula.

Vertical calculations:

Vertical calculation 80 9: The law of division: from the high position of the dividend, first see how many digits there are in the divisor, and then use the divisor to try to divide the first few digits of the dividend, if it is smaller than the divisor, try to divide by one more digit; Except to.

69 + 69 times 99 is an easy off-form calculation.

The vertical calculation of 99 times 69 is enlightened in: quietly old.

—Posture imitation—This is the whole process of the vertical calculation of 99 times 69, and the result of the calculation is equal to 6831.

Vertical step 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 process: Step 1: 3 699=2097

Step 2: 3 699 = 20970

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

Calculation: Extended information "Calculation Results": Perform divisor operations on each digit from the high position of the divisor, keep the quotient obtained from each calculation, add the remainder to the next digit for operation, and then calculate the number of digits from the divisor in this order, and the obtained quotient is combined in order, and the remainder is the result of the last operation.

Problem solving: Step 1: 230 33=6 The remainder is: 32 Step 2: 326 33=9 The remainder is: 29

Step 3: 297 33=9 The remainder is: 0

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