Consistent
: The value of the estimator approaches the value of the parameter as the sample size increases.
How do you estimate math answers?
To get an estimate of the sum, round off all the numbers to the same place value, then
add
them. To estimate the difference, round off all the numbers to the same place value, then subtract them accordingly.

“Front-end strategy” is
a method for estimating an answer to a calculation problem by focusing on
the “front-end” or “left-most” digits of a number. Its strongest application is for addition.
