Round 672,831 to the nearest ten thousand

Well, you just have to take what I said before:

1=ones digit
3=tens digit
8=hundreds digit
2=thousands digit
7=ten thousands digit
6=ten thousands digit

So like previous answers, you just look at the digit after the one being asked

So look at the thousands place. 2,831 or 2,000 since all numbers after that digit is irrelevant

Is 2,000 or 2,831 over the halfway point to 10,000? The halfway point being 5,000

No, it is not so that means 2,831 is closer to 670,000 rather than 680,000

672,831 rounded to the nearest ten thousand IS 670,000
