hero (hero):

Estimation is a process that involves doing a calculation in your head. You sort of round the numbers as close as possible to something that you can do in your head.

It is easy to simply compute something like 4 x 20

hero (hero):

that would be a rough estimation.

hero (hero):

It's a rough estimation because it is off by nearly 20 units.

hero (hero):

But it does make sense because 4 > 3.64 and 20 > 17.06

hero (hero):

We would expect the exact calculation of 3.64 x 17.06 to be less than that.

hero (hero):

To be less than that of 4 x 20
