Sloppy math problems? Sloppy when calculating 40 mouths 5?

1800-（x）】/25+192

Calculated from left to right, it is still 1800-x first, then divide by 25 with the difference, and then +192

The result is the same, so the correct answer is 1968

If you forget the brackets, according to 1800-x 25+192=1968, then x 25=1800+192-1968=24x=24*25=600

Original formula = (1800-600) 25 + 192 = 1200 25 + 192 = 48 + 192 = 240

Same as the above question, it should be (1800-() 25+1927=1800 25-() 25+1927 and the small sloppy calculation is 1800-() 25+1927, we can see that the result becomes larger: 1800-1800 25=1800-72=1728, so the correct result is: 1968-1728=240

Solution:1The analysis question means:

The sloppy approach is: 1800-()25+192=1968. Based on this equation, the value of the parentheses can be calculated. Then calculate the result according to the correct expression, and you can do it.

2.The calculation is as follows:

24x25

When Xiao Ma Hu was doing a calculation problem (1800-() 25+192, he forgot the parentheses, first divided the number in () by 25, and then calculated 1968 from left to rightQ: What is the correct answer?

A: The correct answer is 240

, so the little sloppy looks at it as 11, and the correct one should be.

Knowledge points: solve in errors.

Analysis: Turn 11 into a small quarrel and slowly rise modulus to change envy.

So the original number should be, and the correct answer is.

, the decimal that is mistaken into an integer is, the original =

Summary. When 10 + mouth 5, the addition of the first calculation, the result is 5, which means that the last step of division is 25 5 = 5, so the first step of addition results are 25, so the box is 25-10 = 15, so the correct equation is 10 + 15 5 = 10 + 1 = 11

Who knows this question: Little sloppy is doing the calculation problem (10

The answer is 40.

The correct calculation is: 3 20 , = 3 +60;Put the brackets to see the wheel and lose the sedan chair to take the calculation is: 3 + 20;3 +60 (3 +20)=3 +60 3 Fanhong 20=(3 3 )60 20)=0+40=40;

According to the order of the four mixed operations of integers, the parentheses are lost, and the order of operations is changed, and the multiplication is calculated first, and then the addition.

What does the little sloppy do in calculating 10+()5=5?

Bracket minus 25

10+？5=5 again

Bracket minus 25

It is recommended to send the question to the teacher.

When calculating 10+ mouth 5, the addition of the first calculation, the final result is 5, what is the correct result?

The correct result is 11, 10 + 15 5 = 10 + 1 = 11

When 10 + mouth 5, the addition of the first calculation, the result is 5, indicating that the last step of division is 25 5 = 5, so the first step of addition is 25, so the box is 25-10 = 15, so the correct formula is 10 + 15 5 = 10 + 1 = 11

Dear, have you learned.

So how much homework do we need to complete here, dear, you can tell the teacher, and the teacher can answer all of them for you in detail.

Teacher, I still don't understand.

When 10+ mouth 5, the addition of the first calculation results in 5

The last step of division is 25 5=5

So the first step of addition results in 25

So the box is 15

So the correct equation is 10 + 15 5 = 10 + 1 = 11

Mixed brigade and brigade joint operation, the first town accompanies the multiplication method in the calculation of addition and subtraction, the same level of operation is calculated in the way from left to right, and the one with parentheses is counted in the parentheses. 

He said that the addition of the first calculation, and the division of the second calculation.

yes, so let's do the addition first.

I counted 15

So the box is 15

You're right, you're great.

He calculated the wrong way of calculating it, and the final result was to follow the correct calculation method.

Mixed brigade and brigade joint operation, the first town accompanies the multiplication method in the calculation of addition and subtraction, the same level of operation is calculated in the way from left to right, and the one with parentheses is counted in the parentheses. 

When calculating a multiplication with a zero at the end of a multiplier, he forgot to add zero to the end of the product, and the result was 648 less than the correct product, which was 6480.

648x10=6480

For example: 1. Write a 0 less, indicating that the correct product is reduced by 10 times, so that the correct product in the sail is 10 times the wrong product;

2. The correct product is larger than the wrong product: 10 1 = 9 (times) is exactly 4005.

3. Wrong product: 4005 (10 1) = 445

4. Correct product: 445 10=4450

The product of algebraic structures is trapped in the mountains.

The concept of the product of algebraic structures is often used when studying algebraic structures in abstract algebra. The product of two algebraic structures is generally defined as a new algebraic structure in which the elements of two algebraic structures correspond to a new element through a binary mapping, and then the new elements are formed by appropriate rules.

If the number of elements of two algebraic structures is finite, then the number of elements of their product will be the product of their respective elements. This is also one of the reasons why this new algebraic structure is called a product.

If: the result of a positive match or omission should be:

If the question of Xiao Sloppy is also the same as that of Zhirot, it should be: regimental army.

Summary. Dear, what's your full topic? <>

<> sloppy in the calculation of 50 (mouth-3).

Dear, what's your full topic? <>

<> ignore the parentheses and calculate the multiplication and then subtraction, how much does it differ from the correct answer?

Dear, the answer is a difference of 147.

Can you explain?

Or give the steps.

The correct value should be 50 mouths -150, that is, the value with parentheses, if there is no parentheses, this formula will become Min Yanfeng 50 mouths -3, these two bridges in the formula 50 mouths are the same, 150 and auspicious book 3 difference 147 oh <>

How did <>150" come out? Can you be more specific? Thank you!

Extended Extension] This method of causing wrong calculation problems due to mistakes, I generally do this1First according to the clan letter according to the correct practice of Kuansun to make a trillion wheel 2And then according to the wrong practice, we also get a number or formula 3The difference between the two formulas can be found.

50 (mouth-3) = 50 mouth-50 3=50-150, such a process, only if you look at the core of the mountain, is to remove the bracket potato digging <>

The correct product is 9000.

The analysis process is as follows:

When Xiao Sloppy did the multiplication calculation, he regarded one of the factors of zhi 45 as 54, and the result was 1800 more than the correct product. Available:

Another factor 45 = product 1.

Another factor 54 = product 2.

Product 2 - Product 1 = 1800, we get: (54-45) Another factor = 1800, get another trouser bucket factor = 200.

This gives us the following: 200 45 = 9000.

No. Because it is possible for the OC to be outside of the AOB.

The first type is AOC = BOA+ BOC

The second type of AOC = BOA BOC

aoc=55°

(□+50)×4-[□4+50]

The result of the sloppy calculation is less than the correct result, with a difference of 150.
