To me, it's a way of simplifying a number.
For example, I go on a car journey of 32.561km. When talking to my old Mum, I might say I went for a car trip for about 30km. In other words I rounded to the nearest 10. Later on, talking with my son, I might say, I went on a 33km car trip. It's an approximation that depends on the circumstances (certainly in practical terms).
Using money, say something costs $292.45c. I could say it's about $300 (rounded to the nearest $100), or $290 (rounded to the nearest $10) or $292 (rounded to the nearest $1)
It is very useful.
20 rounding units. 20.0 rounding tenths 19.8 rounding hundredths 19.76 rounding thousandths 19.765 rounding tenthousandths 19.7649 rounding hundred thousandths
If you are rounding to 100ths it is 1.73 . If you are rounding to 10ths it is 1.7 . If you are rounding to integers it is 2 .
The process of rounding is the same no matter what place you're rounding to.
-- If rounding to the nearest 300, then 749 is. -- If rounding to the nearest 200, then 699 is. -- If rounding to the nearest 150, then 674 is. -- If rounding to the nearest hundred, then 649 is. -- If rounding to the nearest twenty, then 609 is. -- If rounding to the nearest ten, then 604 is.
Rounding is a form of estimation.
the mathematical skill is rounding 5 or above go up 4 or below go down
Decimal numbers in calculations often display a spurious degree of accuracy. By removing these unnecessary digits, rounding can simplify mathematical operations without compromising the results.
There are no set rules about rounding numbers, so when rounding numbers, mathematical rules about rounding can be used. For example, 14 would be rounded to 10, but 15 would be rounded to 20. For another example, 1144 is rounded to 1140 and 1145 is rounded to 1150.

It depends on what you are rounding by. If you are rounding by ten-thousands=80000 If you are rounding by thousands=85000 If you are rounding by hundreds=84700 If you are rounding by tens=84650
That depends on how you are rounding: Rounding up = 6.33 Rounding down = 6.32 Rounding nearest = 6.32
That would depend on what you were rounding it to. If rounding to the nearest whole number, then it does not need rounding. If rounding to the nearest ten, it would be 420. If rounding to the nearest hundred, it would be 400.
rounding is an example of a guess .
Rounding to odd.

If you are rounding to 100ths it is 1.73 . If you are rounding to 10ths it is 1.7 . If you are rounding to integers it is 2 .
You can calculate 3444 times 670 without rounding or you can estimate it WITH rounding. But you cannot estimate it without rounding.
