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

What is the definition of front end estimation?
When using front-end estimation, we add or subtract the front digits, and then adjust for a more accurate estimation by estimating the sum of the digits to the right of the decimal point.

What is front-end estimation in math?

Why is it smart to use rounding on front end estimation after finding an answer?
By using front end estimation, the numbers that you start of with have only one significant digit. It is, therefore, nonsense to have an answer with loads of significant digits.
