Round 543,873 to nearest ten thousand

For this case we have the following number.
 543,873

 1) Remember that when rounding the number to the nearest tousand, the number must have the first three digits (from right to left) equal to zero.

 2) The fourth digit of the number (from right to left) must be rounded to the next number only if the third digit (from right to left) is greater than or equal to 5.

 3) Following steps 1) and 2) we have the number rounded to the nearest tousand is:544,000
