What is the estimate of 543?

Answer 1

First, note that 3 is less than 5; so we'll round 543 down to 540.
Then, note that 4 is also less than 5; so we'll round 540 down to 500.
5, however, is greater than or equal to 5; so we'll round 500 up to 1,000.
Finally, we note that 1 is less than 5; so we'll round 1,000 down to 0.
0 rounded is 0, so our estimation is complete and our estimate is 0.
