How much is a 253 times 17 estimate?

253 into 17, the estimate is about 4,005, I think this estimate is still correct, or the estimate is about 5000

253 17, to make an estimate, the detailed steps are as follows.

253 can be seen as 250 and 17 as 20.

So it becomes 250 20 = 5000

253 17 I'll do a simple calculation for you, it's probably more than 30,000, which is a relatively accurate number.

253 times 17, if you estimate, you can choose to use 250 20 to estimate, but the value is recommended to subtract 700, this estimate is more appropriate.

253 17, estimated put 253. Rated 250, 17, rated 20 their score. That's 250 20, that's 5000

253 times 17 is estimated to be about 5000 because 253 17 250 20 = 5000

You can estimate it as 250 20, which is 5000, which is about this number, that is, 17 is 20 and 250, 13 is 250, 250 20 = 5000

253 17, the preliminary estimate should be more than 4000 and less than 5000, and the specific calculation must be columnar.

The calculation is as follows.

If rounded, keep the hundreds.

The answer is about 4300

If we are 253 17, we can use 250 20 to get 5000. Because 17 is less than 20, it should be equal to more than 4000.

That's about 250 20 = 5000, and then subtracting 750 equals about 4200.

When estimating 253 17, you can first calculate 200 17 The number is 4300, 50 times 17 equals 850, plus 5150 plus 3 times 17 equals 51, and finally equals 6201

253 10 Seven households, I should be in more than 1000.

253 17, in the end it's about a few hundred or a few dozen one, this can be estimated.

53 17 Aunt, what is the approximate budget? These 31,17 words can be estimated according to his estimates, which are generally more than two thousand.

This 253 17 estimate is about how much, this can be estimated as 200 20, this estimate, you have to make it up to an integer, so it will be easier to estimate.

253 can be split into 250 and 3.

Then the estimates were made by multiplying the upper three by seventeen for the two five hundred and seventeen families.

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

This can be simply multiplied by 253 by parentheses 20-3 and then separated.

Hello, 253 17 = 4301 4300

When calculating an estimate, we estimate the result of multiplying two factors.

If this thing is estimated, the European style calculates it well, and generally speaking, it is okay to approximate it.

253 17 Estimating heavy rain is very simple and very important It feels very reasonable.

253 17 is estimated to be approximately equal to more than five thousand.

In the case of this multiplication, it should be possible to use the estimation method to multiply it first, and then you will know how much it is.

Twenty-five, how much does Sansheng Siqi estimate? You need to know how to talk to people.

146 times 25 is estimated to be 3650. The calculation process is as follows:

146x25

146x（30-5）

146x30-146x5

So 146 times 25 is estimated to be 3650.

Nature of multiplication calculations:If the dependent variable.

f with the self-varying volume.

x1，x2，x3，…, there is a direct proportionality between chain lead xn.

and each independent variable is qualitatively different, and without any one of the independent variables, the dependent variable f loses its meaning.

in probability theory. Brother Zhongzhou, an event, the result needs to be divided into n steps, the first step includes m1 different results, the second step includes m2 different results, and the nth step includes mn different results. Then this event may occur n=m1 m2 m3 ......mn different results.

321 multiplied by 19, that is, it can be seen that there are 19 321 in the judgment of fierce and cautious Jixiao, and it seems that the error is relatively large when it is seen as about 20 321, so it is estimated and subtracted by one 321, and the error is solved.

321 20 = 6420, 6420-321 = 6099, estimated result 6100.

You're unlucky:

The answer to the rent round is as follows:

Estimate the suffocation.

I hope the old man can help you, the correct answer.

Your thumbs up may be my motivation to continue to help others.

258 times 15 can be used to estimate the Qiaoye difference in this way: 258 is considered to be 300, rounded off, then 300 times 15, and finally 4500.

258 15, if the method of estimation is used. The valuation should be around 4000. In fact, the exact number is 3870.

Approximately equal to 1660.

72x23=1656

Rounded, so go into one.

74 206 = 15244, so the final result 15244 can be checked by division with 15244 74 = 206, and it can also be calculated with another division, 15244 206 = 74, so the final result is the same as the original formula to prove that the result is correct, and the final result is 15244.

It can be estimated that 75 200 = 15000

So, 74 206 is about equal to 15000

Hello, according to your question, this question should do this.

Since we are looking for the estimation result, we can think of 12 as 10 and 26 as 30 columns as 12 26 10x30 = 300

So the estimate is 300

According to your description, it can be understood like this, first 10 26 = 260, followed by 2 26 = 52 If estimated, 260 + 50 = 310, thank you for your understanding and support!

Let me do the math for you, 12*26=(10+2)*26=260+52=260+40+12=300+12=312, do you understand? It's very simple, I hope it helps you, for reference!

Hello 71 is estimated at 70If 23 is estimated to be 20, then 70*20=1400, so the estimation result is 1400

It depends on who you are going to make an appointment. If it's about a single digit, it's 1630; If it's about ten, it's 1600; If it's about 100, it's 2000

This approximate valuation, you can use 23 70
