To round off 14494 to the nearest ten thousand you have to first locate the number in the ten thousand place, which, in this case, is 1. Now to round you need to see if the number after the 1 is greater than or less than the number 5 because if it's greater than 5, you round up, if not, you round down. Since it's 4, you round down so your answer would be 10000.
