No, it is a more precise procedure than that.
Yes. 12300 rounded to the nearest hundreds is 12300. No problem!
Rounding to the first digit is simply called rounding. This will make the number equal to the same as what the number truly is.
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.
An estimate is an educated guess based on prior knowledge. Rounding off is knowing the exact value but rounding it to the nearest whole number.
The number 4.5 is the same when rounded to the nearest tenth and the nearest whole number. When rounding 4.5 to the nearest tenth, it remains 4.5, and when rounding to the nearest whole number, it rounds up to 5. Therefore, 4.5 is unique in this regard.
When rounding a number, if the digit to the right of the rounding place is exactly 5, you typically round up. However, if you're following the "round half to even" rule (also known as "bankers' rounding"), you would round to the nearest even number. For example, rounding 2.5 results in 2, while rounding 3.5 results in 4. Thus, depending on the rounding method used, a 5 can either stay the same or change.
Look at the place you are rounding off. Look at the number to the right of it. If the number to the right is 4 or less, the rounding value stays the same and every digit to the right of it goes to zero. If the number to the right is 5 or greater, the rounding value goes one higher and every digit to the right of it goes to zero.
Any number between 455.5 and 464.5 could be rounded to 460. When rounding a number, if the digit to the right of the rounding position is 5 or greater, the rounding position is increased by 1. If the digit is less than 5, the rounding position remains the same. Therefore, any number within this range would round to 460.
When you're rounding, the place you're rounding to will either stay the same or go up by one. Everything to the right of that place will turn into zeros.
no actually
Rounding is closer because the amount added to one number is the same as the amount subtracted from the other number which makes the answer match exactly.
982,400 is 982404 rounded to the nearest rounding number.
