There is no difference between rounding up and rounding off. The only thing is that when you round off you drop some numbers.Like in 74,329 the 10,000 would be 70,000.
The answer for what is 16 when rounding off when the one is underlined is 20.
No, it is not. Estimating may be rounding but need not be.
There is no universal "better". Rounding off is a trade-off between reducing the accuracy and simplifying calculations. Also, if there are other numbers in an addition that are rounded to the nearest hundred, there is no point in rounding your number to the nearest ten.
Under conventional rounding, it wouldn't be. If you were rounding to the nearest 50.27, it would be.
It depends what you're rounding off to. If you're rounding off to the hundredths, you get 9.86 If you're rounding off to the tenths, you get 9.9 If you're rounding to the whole number, you get 10
It depends on the level to which you are rounding off.
steps rounding off number
how do i turn off the automatic TX report

In whole numbers, rounding to the nearest ten is better. And in decimals, rounding to the nearest hundreth is more accurate.
i had the same problem too :(.i couldn't figure it out so what i did,is when i was done with it i turned the battarie around so it turned off
No, it is not. Estimating may be rounding but need not be.
It depends on which place you are rounding to. If you are rounding to the tenths place, 17.15 rounds off to 17. If you are rounding to the hundredths place, 17.15 becomes 17.2.
Im not sure actually. But rounding to the nearest number means its easier probably.
Rounding off is a important part of mathematics and a very handy tool for everyday life.
