What is an estimate for 0.02?

The front end estimate is 0.02 but estimating a single number, in isolation and without context is a complete waste of time. If I had to add 0.02 to 1 trillion, I would estimate it as 0. If I had to add 0.02 to 0.0000000001, I would use the number as given - not an estimate.Also, if I needed to use it for multiplication or division I would not use an estimate but the actual number.


Would you use a benchmark of 1000 to estimate the number of shoes in your classroom?

Yes


What is the estimate of 1682?

The front end estimate is 2000. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 1682 to 1 trillion, I would estimate it as 0. If I had to add 1682 to 0.0000000001, I would use the number as given - not use an estimate.


What is an estimate for 282?

The front end estimate is 300. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 282 to 1 trillion, I would estimate it as 0. If I had to add 282 to 0.0000000001, I would use the number as given - not use an estimate.


What is the estimate of 282189?

The front end estimate is 300000. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 282189 to 1 trillion, I would estimate it as 0. If I had to add 282189 to 0.0000000001, I would use the number as given - not use an estimate.


What is a estimate for 18759?

The front end estimate is 20000. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 18759 to 1 trillion, I would estimate it as 0. If I had to add 18759 to 0.0000000001, I would use the number as given - not use an estimate.


How do you estimate 364?

The front end estimate is 400. But estimating a single number, in isolation and without context, is a complete waste of time.If I had to add 364 to 1 trillion, I would estimate it as 0. If I had to add 364 to 0.0000000001, I would use the number as given - not use an estimate.


How do you estimate 555?

The front end estimate is 600. But estimating a single number, in isolation and without context, is a complete waste of time.If I had to add 555 to 1 trillion, I would estimate it as 0. If I had to add 555 to 0.0000000001, I would use the number as given - not use an estimate.


What is the estimate of 33?

The front end estimate is 30. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 33 to 1 trillion, I would estimate it as 0. If I had to add 33 to 0.0000000001, I would use the number as given - not use an estimate. Also, for multiplication, I might estimate it by 33.33... and then use 100/3 for calculations.


What is the estimate for 779797?

The front end estimate is 800000. But estimating a single number, in isolation and without context is a complete waste of time.If I had to add 779797 to 1 trillion, I would estimate it as 0.If I had to add 779797 to 0.0000000001, I would use the number as given - not an estimate.


How do you estimate 117?

The front end estimate is 100. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 117 to 1 trillion, I would estimate it as 0. If I had to add 117 to 0.0000000001, I would use the number as given - not use an estimate.Also, if I had to divided the number by 13 I would use 117 since 117/13 = 9 but if I had to divided it by 24 I might estimate it as 120 because 120/24 = 5.


What is the estimation for 130?

The front end estimate is 100. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 130 to 1 trillion, I would estimate it as 0. If I had to add 130 to 0.0000000001, I would use the number as given - not use an estimate. Also, if I had to divide it by 25, I would estimate it as 125 since 125/25 = 5, whereas if I had to divide it by 12 I would estimate it as 132 because 132/12 = 11.
