How can 3 65 0 5 66 35 2 be easily calculated?

So we can do a detailed calculation through the simple process operation above, and the answer we get is 35.

Analysis of the clever calculation process.

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:

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

In this equation, it can be written that the result of both equations is the same. So.

Dividing by a number is equal to multiplying by the reciprocal of this number, and the reciprocal of 2 is so the equation can be written.

Hello, this question has been answered.

If you are satisfied, please click.

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

According to the principle that dividing by a number is multiplying by the reciprocal of a number, the formula can be reduced to :

Solution: Original formula = multiplication and multiplication (multiplication of 70 = 35.)

Equal to 35. Dear, give it one.

The ontology mainly examines the simple calculation of the distributive law.

a*b+a*c=a*(b+c)

Calculate the data in parentheses first to get the whole ten, or the whole hundred, or thousand, and finally multiply it to achieve easy calculation.

The following calculations can be made.

According to the law of association, (

The calculation process is as follows:

Additive Properties:From addition to exchanging the law of revelation and the law of union.

You can get: several additions are added, and the position of the additions can be arbitrarily exchanged; Or the one who digs up the knowledge returns first adds up a few additions and then adds them to the other additions, and judges the sum of starvation to be unchanged.

For example: 34 + 72 + 66 + 28 = (34 + 66) + (72 + 28) = 200.

(Nian Hongji trembling 444 + 556).

We hope we can help you!

Return to the town of 40+2).

The coarse matching law of multiplication and leakage of collapsed liquid is used.

Hello dear. The easy formula is.

Dear, is there anything wrong with this question? Or 64?

Questions. Questions from the child's workbook.

Questions. Okay, thanks.

Dear, no thanks, if you can, please give me a thumbs up, thank you for asking. Given.

Can it be easily calculated?

Dear, I'll take a look.

The easy way to 666 is to transform it into 666 first, and then extract the 666 from the stuffy stove and pretend to be 666 (

The simple calculation of line dispersion and square dispersion method is as follows. Punch the line.

This problem is very simple with a simple method, the first item of the wide chain state has 666, and the latter item is called yes, you just need to make it 666, and then at the same time, of course, 67 will become. This makes it possible to extract the common factor of 666. In the parentheses at the back is 3 points 3 + 6 points 7.

Doesn't these two numbers add up to ten? Then multiply 666, and the final result is 6660?

The tenfold expansion of your good friend is 666, so Duzi Huye makes oranges with 666, and you can bring out 666, which is +6 points seven equals ten.

Six hundred and sixty-six 10 is equal to 6660

Fix the back formula and it becomes 666

In this way, you can extract 666, and the rest will not stop Mingzai from saying it with my more Jian Huairan.

The easiest way to calculate this is to find the similarities and come up with them to become 65*(

Summary. Hello, if it is and 24, then it is:

But generally speaking, it can be rounded. <>

Calculate with ease.

Hello, I am Mr. Tongna Yinfang Tengfei! I've seen your problem. Since the text of the answer needs time from the bureau, please be patient and wait for 2 3 minutes Yo Be sure not to end the order directly, so that you can't see the answer I sent you Minbi, thank you

Hello, the answer is. If we observe the equation, we can find that there are both multiplications, so the calculation and elimination process is as follows: = The problem is the relevant knowledge of multiplication. I hope my hand can help you. [laughs Bi Qiaopei].

It's 24. No.

Hello, if the early fruit of the spike is and 24, then it is: = but generally speaking, it can be rounded. [laughs and guesses the sparrow and thinks of Lee].
