Can you explain what the difference between rounding and front end estimation is? For example round 82672761= and front end estimate 64891807= .

Front end estimation generally produces a better estimate of sums or differences than rounding before adding or subtracting.
How to Estimate a difference by front end estimation
* Subtract the digits of the two highest place values
* Insert zeros for the other place values
*
* Example: 7396 minus 3745 is estimated to be 3600 by front end estimation (i.e. 73003700).
Now Rounding:
82672761
83002800
5500
You do the front end estimate.
