Underestimate
If you have rounded up, it will be an overestimate. If you have rounded down, it will be an underestimate.
It's an overestimate. The actual total is 1.61
Since the exact answer is 1.61, 2 is larger than 1.61 and hence an overestimate.

To determine if an estimate is an overestimate or an underestimate, compare the estimate to the actual value or a more accurate reference point. If the estimate is greater than the actual value, it's an overestimate; if it's less, then it's an underestimate. Additionally, consider the methods used for estimation—if they generally involve rounding up or using conservative assumptions, they may lean towards overestimation, while rounding down or being overly cautious may lead to underestimation.
Advantages and disadvantages of overestimate and underestimate
overestimate
Most people would estimate that as 6 (an overestimate) - 4 (an underestimate) which would estimate the answer as 2, which is an overestimate.

To determine whether 83790 is an overestimate or an underestimate, we need context regarding what it is being compared to. If 83790 is meant to represent a quantity or value that is expected to be lower, then it is an overestimate.

It's an overestimate. The actual total is 1.61
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.
