Estimating is neither better nor worse than rounding. The two are used for different purposes.
No, it is not. Estimating may be rounding but need not be.
They are not.
Rounding, you see the number and just make it look neater or easier to use. Estimating, you guess a number.
Rounding?
Rounding factors can lead to underestimates or overestimates: the outcome depends on the rounding.
Estimating is a guess that should be close to the answer. Round is rounding a number up to the nearest ten, hundred. Example $345.89 round to the nearest dollar is $345.
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.
By rounding the factors, then quickly multiplying them in your head.
The answer depends on better than WHAT!
if you had an adding sum we would use it and if you were estimating
No,Rounding means reducing the digits in a number while trying to keep it's value similar. The result is less accurate, but easier to use.This is the common method* Decide which is the last digit to keep* Increase it by 1 if the next digit is 5 or more (this is called rounding up)* Leave it the same if the next digit is less than 5 (this is called rounding down)Example: 243 rounded to the nearest ten is 240 (because 3 is less than 5)And estimating is a close guess of the actual value, usually with some thought or calculation involved.Example: Alex estimated there were 10,000 sunflowers in the field by counting rows.Hope the definitions and examples helped you understand that estimating and rounding are not the same thing.
