The 3 is in the ten thousands place so the number to the right of that tells you if you need to tound up or down. Anynumber 5 or higher then you round up. If lower than five you leave it alone.

A number rounded to the nearest 10000, means that the last four digits of that number (on the left of the decimal point) are 0.  
However, if the fourth-last digit to the left of the decimal point is 5 or greater, the number to the left of that is rounded to 1 number higher.  For example, if you were rounding 145293 to the nearest 10000, it would be 150000. 

However, the fourth-last digit to the left of the decimal point in this case is 1.  
Therefore,  31000 rounded to the nearest 10000 is 30000.
