126 9 7 Off Entry Calculation?

The de-entry calculation process is as follows:

Method 1: 126 9 7

Method two: 126 9 7

Method 2 takes advantage of the nature of division: the dividend-being is divided by two divisors consecutively, which is equal to the product of the two divisors.

Off-Sheet Calculations:

Off-form computing is a mathematical term, that is, recursive equation calculation, the operation of writing the calculation process in its entirety, that is, the calculation that is out of the vertical form.

In sibling operations, it is calculated from left to right;

In two-level operations, multiplication and division are calculated first, and addition and subtraction are calculated later.

When there are parentheses, count the inside of the brackets first, and then the outside of the brackets;

When there are multiple layers of parentheses, count the ones in the small brackets first, then the inside of the middle brackets, then the inside of the braces, and finally the outside of the brackets.

If there is a power, the power is counted first.

In a mixed operation, the number in parentheses is counted first, from the smallest to the largest, and if there is a power, the power is calculated first, and then from the advanced to the lowest.

Recursive equation operation rules.

Off-entry calculation process analysis 126 9 7

Solution: Four rules of operation (calculated in order, multiplication and division first, then addition and subtraction, parentheses are counted first, and power is calculated first), that is, the off-form operation (recursive equality calculation) needs to be carried out under the premise of this principle. Problem solving process:

Extended information: The dividend is calculated from the high digit to the divisor, the quotient obtained from each calculation is retained, the remainder is added to the next digit for the operation, 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 process: Step 1: 12 9=1 The remainder is: 3Step 2: 36 9=4 The remainder is: 0

According to the above calculation steps, the combined result is 14

Hello, this off-form calculation is as follows:

Solution: 126 9 7 is equal to (2).

It is known how much the demand out of 126 9 7 is.

Answer: 126 9 7 is equal to 2

In fact, this question is a typical 8 125 1000! If you don't see it, you can extract the common factor 125 and you can see it at a glance 125 (1+7), and the simple calculation of these 4 25 and 8 125 are basic equations!

Solution: 125 7 125 is equal to (1000) It is known that the demand out of 125 7 125 is equal to how much.

x + x y = x 1 + y) Answer: 125 7 125 is equal to 1000

How to calculate the off-entry calculation, this is the clearest explanation I have ever seen.

450 18 = 25, off the calculation, you can first calculate 45 18 = 2 more than 9, and then use the hidden 9 10 18 = 5, the stove did not rush the last 2 10 + 5 = 25, so you can check it, 25 18 = 450, the final result of the spring is 450 18 is 25.

At this time, multiplication is used to calculate the distribution rate of addition. There are also places called "extracting common factor bridges".
