Estimation can be very useful because when we do not know the actual correct answer we can just estimate. Estimation helps you check your answer by seeing if the estimate is close to the result you got. You can also estimate first to know approximately what result you should expect to get.

Answer:

Estimation is useful when finding actual products and real world solving because, it leads you closer to the answer you are going to be aiming for. For example if a question is 23 x 6 + 1= ? you would estimate around the 100 because it is closer to the answer you will mostly likely create and get.
