## What is the clustering estimation technique?

Cluster estimation can be used to estimate sums and products when the numbers you are adding or multiplying cluster near or is close in value to a single number. Example # 1: Estimate 699 + 710 + 695 + 705 + 694 + 715. Carefully examine all the numbers above.

## Why do we estimate in math?
