What is front-end estimation?

It means using only the first non-zero digit (rounded up if required), and replacing all other digits by zero.


What is the Front-end estimation method?

Front end estimation is a quick method to find an estimate of sums and differences, however it is generally not more accurate than the answer produced by adding or subtracting rounded numbers. Take for example a pair of pants and a shirt that are $24.99 and $16.99, respectively. The correct total of these items would be $41.98. Using the method of adding rounded numbers would yield $42 - which is only two cents from the correct total. Front end estimation would yield $40 - which is $1.98 short of the correct total. The use of front end estimation is why stores sell things for $24.99 and $16.99, rather than $25 and $17. It is an open attempt to make the consumer think that they are paying for something at a lower price than they actually are.


You want to estimate 5.25 - 3.3 why would using front-end estimation and adjusting tell you more about the answer than rounding?

Well, darling, front-end estimation involves looking at the leftmost digits to get a quick ballpark figure, then adjusting for accuracy. Rounding just gives you a rough estimate without considering the actual numbers. So, if you want a more precise estimate, front-end estimation and adjusting is the way to go.


How do you compute a square root?

Square roots are computed using the Babylonian method, calculators, Newton's method, or the Rough estimation method. * * * * * Or the Newton-Raphson method.


Miguel has 325 baseball cards and 272 football cards he said he said that he has 597 cards in all is his answer reasonable explain using estimation?

320+270 = 590; yes, it is reasonable.
