Rounding Values before Multiplying

This video shows a detailed example of how to round values before multiplying. The reason for rounding values before multiplying is to estimate an answer close to the solution in a lot less time than it would normally take. For example, in the problems 7.96 x 4, 11.89 x 2, and 28 x 1.03, you would round the decimals up or down to get the following: 8 x 4, 12 x 2, and 28 x 1. The answers will be a close estimation of the actual solution.
