Estimating is the process of making an approximate calculation or judgment about a quantity or value, often used when an exact answer is not necessary or feasible. Rounding is a specific technique used in estimation to simplify a number to a nearby value that is easier to work with, typically by eliminating decimal places or adjusting to the nearest whole number. Both methods help streamline calculations and make mental math more manageable.
No, it is not. Estimating may be rounding but need not be.
Rounding, you see the number and just make it look neater or easier to use. Estimating, you guess a number.
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.
Rounding involves adjusting a number to a specified degree of accuracy, typically to make calculations simpler, such as rounding 4.7 to 5. Estimating, on the other hand, involves making an approximate calculation or judgment about a quantity without exact precision, often using rounded numbers to quickly assess a situation. While rounding gives a precise value based on a rule, estimating provides a broader, more flexible approach to understand or analyze quantities.

They are not.
Rounding, you see the number and just make it look neater or easier to use. Estimating, you guess a number.
Estimating is neither better nor worse than rounding. The two are used for different purposes.
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.
if you had an adding sum we would use it and if you were estimating
Rounding factors can lead to underestimates or overestimates: the outcome depends on the rounding.

Front end estimation is simpler but usually more crude.
