To round, find the place you are rounding to. Then look at the digit just to its right. If that digit is 5 or more, round up. If it is 4 or less, round down. All the digits after the rounding place become zeros.
Rounding 46 382 to the nearest 1000: the thousands digit is 6 and the digit to its right is 3, so round down to 46 000. To the nearest 10 000, look at the 6: round up to 50 000.
