Answer

The use of rounding is helpful when estimating the answer to a problem because it simplifies the problem, eliminating many steps that are needed when all the smaller order digits have to be taken into consideration. For example $628,783 \div 248,837$ can quickly be estimated using rounding. $600,000 \div 200,000 = 3$.

Work Step by Step

Use of rounding can allow a problem to be solved with mental math rather than needing to write out a long solution on paper.
