Front end rounding is using the first or the first two digits to make an estimation. 37145 would be rounded to 40000.
Front end estimation is simpler but usually more crude.
Front end rounding is taking the first digit and making the rest 0. 75 would be 70 in front end rounding.
The name comes from the way you round. Front end rounding is keeping the first number and rounding all the numbers after that.
In front end estimate, one takes the two hightest digits of a number, and then puts zeros on the other place values. This is supposed to product a closer estimate than rounding and then adding numbers. For example... 4496 plus 3745... front end 4400 and 3700 and then add... to 8100 For 4496 and 745... fond end 4400 and 0700, and then add to 5100

Instead of rounding each number to a given place value, we round whatever number is in the front.
by adding or subtracting the values of the digits in the front place
The name comes from the way you round. Front end rounding is keeping the first number and rounding all the numbers after that. To make the last four digits in 10124 a 0, round to the nearest ten thousand. That would be 10000. 10000 is the front end rounding 10124.
