The order before the decimal point is as follows,
(Million)(Hundred thousand)(Ten thousand)(Thousand)(Hundred)(Ten)(One)
The order after the decimal point is as follows,
(Tenth)(Hundredth)(Thousandth)(Ten thousandth)(Hundred thousandth)
The general rule for rounding:
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30
Hence,
13,501 rounded to the nearest ten thousand is 10,000.
