∙ 14y agoSince the exact answer is 1.61, 2 is larger than 1.61 and hence an overestimate.

There is no need to estimate when the exact answer is so easy to find. 55*2 = (50 + 5)*2 = 50*2 + 5*2 = 100 + 10 = 110
The estimate is 1.
6+2=8
Most people would estimate that as 6 (an overestimate) - 4 (an underestimate) which would estimate the answer as 2, which is an overestimate.
You know if an answer is an over or underestimate because if the last 2 # is 5 and over, it is an overestimate. If the last 2 # is 4 and under, it is an underestimate. Ex: 345 answer if you were estimating 350 over. Ex: 232 if you were estimating your answer would be 230 and that is under.

To the nearest integer, 2
For multiplication or division, the only reasonable estimate is -2.

100,000,000 that means 100 million (this seems like a gross overestimate. half of the population of Brazil goes to carnival in Rio? I have actually gone. It is crowded but not that much. Maybe this estimate is recounting people for each day. Officially Carnival is only 4 days but in practice there are events spread over 2 weeks.)
201 x 2 = 402 If you had to, you could estimate 200 x 2. The answer will be two more than that.
The answer being 0.5456, the digit 2 can not be a good estimate since it is not close.
