Recursive equation calculations.

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: first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier by each digit from the last digit, 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 multiplier first, and finally the product is reduced by the corresponding multiple;

Problem solving: Step 1: 5 314=1570

Step 2: 1 314 = 3140

According to the above calculation steps, the combination result is moved to the left by 4 decimal places, and the product is in doubt, please ask and be satisfied.

So through the simple calculation above, the final answer is:

According to the inscription column, it is calculated as follows:

The easy way?

This question is decomposed by the decomposition method. One.

This problem is not easy to calculate, just multiplication and then subtraction.

The result can be calculated by calculating the calculation method.

Hair or divide, they are divided, so that it will be much easier to merge the same item with the same item.

Formulas are calculated with formulas, which is the easiest way to do it. g

1. Addition. a. Integers and decimals: the same digits are aligned, added from the lowest digits, and the full ten is one to one.

b. Same denominator fraction: add the invariant numerator of the denominator. Fractions with different denominators: first pass and then add up.

2. Subtraction. a. Integers and decimals: the same digits are aligned, subtracted from the low digit, which digit is not enough to decrease when ten and then subtract.

b. Fraction of the same denominator: the denominator remains unchanged, and the numerator is subtracted. Denominator fraction: first pass and then subtract.

3. Multiplication. a. Integers and decimals: use the number on each bit of the multiplier to multiply the number on which digit the multiplier is used, and the last digit of the number is paired with which digit, and finally add the product, the factor is a decimal place, and the number of decimal places of the product is the same as the number of decimal places of the two-digit factor.

b. Fraction: the product of the multiplication of the numerator is the numerator, and the product of the multiplication of the denominator is the denominator. The results of the first reduction should be simplified.

4. Division. a. Integers and decimals: There are a few digits in the divisor to look at the first few digits of the dividend, (if not enough, look at one more digit), divide to which digit of the dividend, and the quotient will be written to which digit.

The divisor is a decimal number, which is first divided into an integer, and the decimal point in the quotient is aligned with the decimal point of the dividend.

b. The number A divided by the number B (except 0) is equal to the reciprocal of the number A divided by the number B.

Because the sum of products can form integers.

Why do you want to reduce it, teacher.

Questions. Oh, got it, thank you, teacher.

You're welcome! Kiss. 

In fact, this is used to divide and multiply.

Then this problem can also be thought of in a different way, for example, the commutative law of multiplication is equal to (

The easy way?

Hello, it's a pleasure to pretend to be a <> for your mountain

The simple calculation of this problem is as follows: first find the law, yes 3 times, so the base limb.

Simple, complete the trace, clear calculation, balance and report

It is possible to split into 3 ands.

Hope it helps.
