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.
To check the answer to a decimal multiplication problem, you can use the inverse operation of division. Divide the product by one of the original decimal numbers; if the quotient matches the other original number, your multiplication is likely correct. Additionally, you can estimate by rounding the decimals to whole numbers and checking if the estimated product is close to your calculated answer.
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.

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.
It is the multiplication of two numbers which are in decimal form.
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.
Their magnitude is ten thousands.
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.
It is a decimal number whose magnitude is one tenth as large.
The magnitude estimate for 12.2 multiplied by 1.56 is approximately 19.03.
