Question

Explain Estimation of number and give
Some examples.​

Answer 1

Answer:

One very simple form of estimation is rounding. ... This is where you make a long number simpler by 'rounding', or expressing in terms of the nearest unit, ten, hundred, tenth, or a certain number of decimal places. For example, 1,654 to the nearest thousand is 2,000. To the nearest 100 it is 1,700.

Answer 2

Answer:

Estimation of numbers is the process of estimating/approximating or rounding off the numbers in which the value is used for some other purpose in order to avoid the complicated calculations.

Example: 550 + 298: 298 is nearly 300 so an estimate is 550+300 = 850. 550 + 248: 50+48 is nearly 100 so an estimate is 500+200 +100 = 800
