It is difficult to answer the question because, for addition or subtraction, it is often easier to obtain the exact answer! If you line up the decimal points and then follow the rules of addition or subtraction - exactly as they would apply to whole numbers - you will get the correct answer!
Estimation may be useful to check your answer if you are poor at addition or subtraction of integers. But, if that is the case, your estimate is equally likely to be wrong!
