If you have the exact value, why do you need to estimate!
When the exact number is not required, only a ball park figure or an order of magnitude. This could be forced upon you when you do not have exact values for the two quantities involved.
estimate
Estimates are never exact. They are a best guess at what the answer is. They are always going to be approximate.
if you have to do it be exact, answer is 17.95
Ignore the remainder: after all, it is only meant to be an estimate - not an exact answer!
You can estimate when an exact answer is not needed.
If you have the exact value, why do you need to estimate!
over-estimate
over estimate
Your estimate will be greater than the exact number.
Not usually.
there is no need for an estimate - exact answer is 212.80
There are two main situations in which you would estimate:when there is no analytical solution and the only way is to estimate a solution using iteration,when an exact answer is not required or the time or effort required to obtain an exact answer cannot be justified by the improved precision.
