Answer:
2,800
Step-by-step explanation:
Unit - 1
Tens - 10
Hundreds - 100
Thousands - 1,000
From the number, the hundred number is 8.
So look at its right side if the number 5 or above (means you have to add the main number) or not (leave it).
2,826
The 2 (in italic) is lower than 5 so just leave 8 alone. Put all the numbers on the right into 0's.
2,800
