Approximation is rounding the number to a significant figure, decimal place while estimation is the rough answer of numbers being multiplied.

ReplyDeleteEstimation is the rough answer of the equation whereas Approximation is to round up the number to a set decimal place.

ReplyDeleteApproximation is defined as the rounding off of a number to a particular number of significant numbers.

ReplyDeleteEstimation is rounding off of a number to get an answer which is close to the correct answer and can be used in checking.

Estimating is a part of approximation. Approximation consist of 2 things rounding to a significant figure and estimation. Estimation is when you round all numbers in a sum to a significant figure then work it out

ReplyDeleteApproximation means rounding up the number after you have done the sum. Estimation means rounding up both numbers before doing the sum.

ReplyDeleteApproximation is rounding it to a significant figure with a small range while Estimation is to round off the numbers to a number that is easy to multiply and is not too far off from the original numbers.

ReplyDeleteApproximation of a number is very close to the actual number itself. Estimation is only a rough calculation of a number.

ReplyDeleteApproximation is rounding of the the nearest significant figures while estimation is rounding off all numbers in an equation to find the estimated answer easily.

ReplyDeleteApproximation is the act of rounding to a specific significant figure but estimation is rounding off two values to be added, multiplied, divided or subtracted together.

ReplyDeleteApproximation is about the rough rounding up of a number for easier operation.Estimation is guessing the rough value of an answer in a sum.

ReplyDeleteapproximation is rounding down or up a number

ReplyDeleteestimation is rounding numbers fora sum.

Approximation is a number quite similar to the original number while estimation is guessing a number before it is worked out.

ReplyDeleteApproximation is giving a rough gauge that is close to the exact answer...

ReplyDeleteApproximation means that round the numbers to some value while estimation means guess the ans

ReplyDeleteApproximation is roughly rounding a number to a significant figure while estimation is rounding a number for a easier operation.

ReplyDeleteApproximation is changing the answer to the amount of numbers that the question want in the answer.Estimation is the rounding of of the numbers involved in the number statement then finding the answer.

ReplyDeleteestimation is rounding off the numbers before working out the sum. approximation is rounding

ReplyDeleteoff the result of the equation.

ReplyDeleteapproximation means the rough rounding off of two numbers to get the final answer while estimation means the guessing of the final answer.

ReplyDeleteEstimation is rounding off the numbers to get an estimate of the actual answer while approximation is the rounding off of numbers to a specific number of significant figures.
