The difference between the two numbers is 356, and if the subtraction is reduced by 138, the subtrac

Calculate 356-138+138 according to the proposition

Problem solving ideas: The key words in the application problem are average, division is generally used, multiplication is generally used, and addition and subtraction are generally used for who is more or less than whom, and columnar formulas are applied according to the keywords. Problem solving process:

A: At this time, the difference is still 356

Extended Data - Vertical Calculation - Calculation Result: The single digit of the two added numbers is aligned, and then the numbers on the same counting unit are added together, and the addition result is 10 to the high position, and the high level needs to be added to the low level by 1.

Problem solving process: Step 1: 8+8=6 to the high position by 1

Step 2: 1+3+1=5

Step 3: 2+1=3

According to the above calculation steps, the combined calculation result is 356

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

Let the subtracted number be x, and the brief description is y, according to the title.

x-y=356

Then according to the question, the subtraction is reduced by 138, and the subtraction is reduced by 138, and the following answer is obtained.

x-138-(y-138)=x-138-y+138=x-y=356 hope!

Minuend. The sum of the three numbers is 256, where the subtraction is 32 smaller than the difference, ask what the difference is.

Subtracted = minus + poor.

Therefore, the subtraction = 256 2 = 128, the subtraction + difference = 256 2 = 128 and the subtraction is 32 smaller than the difference, that is, the difference - the subtraction = 32

According to the relationship between sum and difference, difference = [128 + 32] 2 = 80, subtraction = [128-32] 2 = 48

Summary. If there is any unclear or incomprehensible point, I will continue to communicate with you to clarify the problem. The difference between the two numbers is 548, and if the subtracted number is reduced by 158, and the subtraction is also reduced by 158, then what is the difference at this time?

Dear, you mean sell well. Your inquiry question has been seen, and it will take some time to interpret, search, organize, and reply to the answers; It also takes some time to type. Please wait.

If there is any unclear or incomprehensible point, I will continue to communicate with you to clarify the problem. 欄

Or the 548 process.

Teach children. Equation of calculation.

This is best done by analogy.

If you compare 5-3=2, the subtractor and the subtracted number will subtract 1 at the same time, and the answer will remain the same.

The difference between the two numbers is 472, and if the subtraction is reduced by 164, the subtraction is reduced by 29, how much is the difference.

x-y=472, then (x-164)-(y-29)=x-y-164+29=472-164+29=337

Let the number of acres to be reduced be a, and the number of subtraction feet will be rushed to be b

then a+b+102=258

i.e. a+b=156

And because a-b = 102

A=129

b = 27 means that the subtraction is 129 and the subtraction is 27

Let the source remainder be reduced to a, and the meiotic rebalancing crack mill is b

then a+b+102=258

i.e. a+b=156

And because a-b = 102

A=129

b=27 means that the number of the reduced buckets is 129, and the minus number is 27

Let the subtracted number be x, and the subusal key is sock Li y, then the difference is x-y by the delay of the notice, x+y+x-y=196

y-24=x-y

x=98, y=61, and the difference is 37

According to the inscription, as long as Zenga is subtracted and subtracted by an equal number at the same time, then the difference will not change. Column calculation: Let the subtraction of Zaokai be a, the subtraction is b, a-b=325, a-75)-(b-75)=a-75-b+75=a-b=325, He Jie Pai replied:

The answer to this question is 325, the difference is the same, the answer is complete, thank you!

That depends on how much is subtracted. For example, 401-76.
