Estimating: Rounding Values Before Adding
Rounding values before adding is a great way to reach an estimation of your final value. The main purpose of estimating is to find a solution that is close to the actual solution but that you can find more quickly. For example, when adding 7,184 + 2,889 + 4,612 + 3,486, you can round the numbers to 7,200 + 2,900 + 4,600 + 3,500 and get the answer 18,200. Again, this is just an estimate of the actual sum of the original numbers. The actual sum would be 18,171.
