The result of the estimate is a little larger than the exact value True or False

For example, 12 33 300 and the exact value is 12 33 = 396, the estimated result is less than the exact value. In estimation, it is generally estimated by "rounding", and when the estimated number is less than the actual value, the result must be less than the accurate value. An example can be given to the answer.

In psychology, estimation is a rough inference or estimation of the results of a quantity or formula of a thing based on specific conditions and relevant knowledge. In mathematics, estimation is an important part of computing power.

Mathematics. 1. Rounding, are not carrying, carrying.

2. Advance method: The advance method is to remove the number of the excess part and add 1 to the last number of the reserved part. The resulting approximation is an excess approximation (i.e., greater than the exact value).

For example, a sack can hold 200 catties of wheat, and there are 880 catties of wheat, and it takes several sacks to fill it up with 880 divided by 200, and the quotient is 4, and the remainder.

is 80, even if it is impossible to use 4 sacks, it must be completed with 5 sacks by the method of progression.

Mistake. Here are some examples:

For example, 12 33 300 and the exact value is 12 33 = 396, the estimated result is less than the exact value.

For example, 12 33 300 and the exact value is 12 33 = 396, the estimated result is less than the exact value.

So the answer is:

From the meaning of estimation, it can be seen that estimation is a rough inference or estimation made on the quantity or result of the calculation formula according to specific conditions and relevant knowledge, and the topic can be quickly judged through estimation, so the statement "because the estimated value is not accurate, so we usually do not estimate" is wrong;

So the answer is:

The result of the estimate is always greater than the accurate value, whether it is true or false.

Is it true that the results of the estimated knot estimates are sometimes larger than the results of the actual calculations, and sometimes smaller than the results of the actual calculations?

If the vertical spike is estimated by the rounding method: the estimated value is smaller than the actual deferral value, for example: ,3;

If the quintile method is used, the estimated value is larger than the actual value, for example:,4 Therefore, the estimated result is larger than the actual value, and it may also be smaller than the actual value, so the stem statement is wrong

So the answer is:

From the analysis, it is known that in the estimation, the number is generally regarded as the number according to the "rounding" method.

Ten, hundreds of slips, thousands or hundreds of dozens...The number of halls is trembling to calculate, so the calculation is more convenient than Xinqing

So the statement is correct;

So the answer is:

From the analysis, it can be seen that if the estimate is underestimated, the estimated value is smaller than the actual value, so the estimation is to estimate the actual value to calculate, and it is wrong to say that the Insight Method is wrong;

So the answer is:

Gusai 354 60 put 354 to see the brother empty base do (360) estimate the result of envy than the accurate value (large) loss.

From the analysis, it can be seen that if the estimate is underestimated, the estimated value of cherry blossom loss is smaller than the original value

Therefore, it is wrong to say that the estimated results are larger than the actual results of the calculations

So the answer is: false

Wrong.

True/False, a term in the field of propositions, is an answer that is selected by right or wrong, characterized by only two answers, and there is a skill in the true or false question, and it is very easy to judge right or wrong if you master it, that is, this proposition has words such as "certainly", "absolutely", "certainly", etc., you should pay attention to it, and the probability is wrong.

Some of the test questions have a lot of words and long sentences, and they contain a lot of content that can exist independently. Some of them are correct and some are incorrect, in which case the test taker's judgment should be based on the overall content of the question. As long as one part of the test is wrong, the whole test should be considered wrong.

The presentation of true/false questions is generally divided into two types: direct conclusion or indirect conclusion. The indirect conclusion style is characterized by the statement of the right and wrong terms first, and the test taker must first reason about the right and wrong terms before reaching a conclusion. The statement of the question itself in the form of a direct conclusion is a judgment sentence.

Candidates can make a direct judgment on this and can draw conclusions without going through loose reasoning. The line of thinking of recall, discrimination, and difference definition is the way to answer this kind of judgment question.

Although the estimation results are not accurate, they are very useful in life, for example, how many students are in a school, as long as you know the number of students in a class and the number of classes, you can quickly get the number of students in this school

So the answer is: spring morning pants.
