Estimating help determine the order of magnitude of the answer. It is, therefore, a simple matter to place the decimal point is such a way that the order of magnitude of the calculated answer matches that of the estimate.

An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.

A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.

Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size).

Vector multiplication is one of several techniques for the multiplication of two vectors with themselves. A vector has a magnitude and direction.

Apparently a magnitude estimate is just a estimate just closer to the actual answer.

If you have no clue about how decimals work then getting an estimate for the answer gives you an order of magnitude which can help in placing the decimal. But if you are even a bit clued up, estimating will not be necessary.

It is the multiplication of two numbers which are in decimal form.

Because conversion in the decimal system is based on multiplication (or division) by powers of ten. Each multiplication by ten is equivalent to moving the decimal point one place to the right.

Their magnitude is ten thousands.

It is a decimal number whose magnitude is one tenth as large.

OOM (Order of magnitude) estimate

The number is already in decimal form so why would you want to estimate it in decimal form???

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

1000

Because until that time there is nothing to put the decimal point in!

when both factors in a multiplication problem are rounded up to estimate the product, the estimate is an overestimate.

To estimate the magnitude or amount of damage it could cause to infrastructure and environment.

Either or both.

It is a bit confusing. An order of magnitude is a factor of 10, but an order of magnitude estimate is more like a factor of 3, or the square root of 10. In some cases it is simply a "ball park" estimate. For example if a company give an order of magnitude estimate for a major construction project of 10,000,000 dollars, it could be anywhere from 3 million to 30 million, but usually it means roughly 10,000,000, give or take a few million.

900 is an estimate. But why would you want to estimate such a simple calculation?

the answer is yes because you can estimate any numbers

The magnitude or value of the number.

Neither. The number of digits after the decimal point is a measure of the accuracy, not magnitude.
