The Answer will be lower the the actual sum
841 would round down to 840 and 362 would round down to 360. So 840+360=1200. The sum is about 1200.

A mathematician in a hurry or one who is only interested in an approximate answer does it.
106 + 091 = 197 100 + 100 = 200 Answer: 3
You can calculate 3444 times 670 without rounding or you can estimate it WITH rounding. But you cannot estimate it without rounding.
400 + 500 = 900
When all the addends in a sum are close to the same number, it is called "rounding." Rounding helps simplify calculations and provide a quick estimate of the total.
