It depends on the person to think if estimation is helpful. If you get a math equation like: 24 + 34 + 12 = ? And the question asked you to estimate than you can do: 20 + 30 +10 = 60 and the you know that your answer is close to 60.
Estimation can also be used when you need to guess ~ For example:
How many jelly beans are in this group? You can estimate the correct answer without counting them. Let's say there are 80 jelly beans and you guest 75. That is estimating because you would take the time to think and you would OBVIOUSLY not guess 10.
Sorry if I wrote too much...
It is helpful because when you are finished estimating (for example: multpliying, diving, adding or subtracting) it's like checking your work that's why it can be helpful to estimate before finding the actual product.
Yes. (True)
Estimating is not as helpful when multiplying very small numbers because the numbers aare very easy to answer
An article on cost estimating in the building construction field, admittedly from an out dated source although the principles are still the same, is at http://www.inquirewithin.biz/Vol2/Estimating/estimating_foundations.htm.

It can be very helpful, so the question is inappropriate.
It is not as helpful when multiplying very small numbers because the numbers are going to be very east to answer. That is why estimating is not as helpful when multiplying very small numbers.

because it is helpful so u can round to finds answer also a lot people like rounding.
Yes
True
It is not in the least helpful because the number is already given to the nearest thousands. So estimating 17 472 000 to the nearest thousands to get the answer 17 472 000 seems totally and utterly pointless.
Yes. (True)
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.
Early estimation can help give an indication of the answer.
I just read the answer and it doesn't help what so ever
explain why estimating is helpful. use at least one sentence to explain.it is 2 1/4 =0.7
