Answer 1

Overestimate because the answer is 1.61

Answer 2

Wesley made the correct estimation if numbers are rounded off.

He did over estimation, if normal calculation is considered.

Explanation:

Wesley estimated 5.82 - 4.21 to be about 2.

Let us make fair estimations in round figures.

5.82 can be rounded to 6.

4.21 can be rounded to 4.

Now,
`6-4=2`

In other way, we can see that
`5.82-4.21=1.61`

Here he over estimated.
