an estimating technique in which the front digits of the addends are added and then the sum is adjusted for a closer estimate
2,000. A front-end estimation just means to round it by the greatest value, in this case the thousands.
It is 200.
A front end estimate is 900.

Front end estimation generally produces a better estimate of sums or differences than rounding before adding or subtracting. How to Estimate a sum by front end estimation * Add the digits of the two highest place values * Insert zeros for the other place values * Example 1: 4496 + 3745 is estimated to be 8100 by front end estimation (i.e. 4400 + 3700). * Example 2: 4496 + 745 is estimated to be 5100 by front end estimation (i.e. 4400 + 700).

Front end estimation- An estimation method in which the front digits are added or subtracted
One way is to do front end estimation!
8000 + 3000 = 11000
8 + 11 = 19
The front end estimate is 700 + 1000 = 1700.
