What are some benefits of front end estimation in multiplication?


Quick Answer

Front end estimation makes a multiplication problem simpler to solve without a calculator by providing an estimation of the product of the original values. While the solution only provides an approximate answer to the original equation, the answer is generally close enough to work as a guideline for everyday calculations.

Front end estimation provides an easier way to approximate a calculation without a calculator by reducing the number of figures used in the calculation. The process relies upon rounding the left-most value of the figure and then replacing the remaining number places with zeros before completing the operation.

For example, the equation 678 multiplied by 423 becomes 700 multiplied by 400 when using front end estimation, thereby reducing the total number of values to be multiplied from six to two.
