how to round off 8,008,278 to the nearest ten thousand.

First let's name all the digits, starting at the far right and moving
to the left.

8 (on the far right) is the one's digit
7 is the ten's digit
2 is the hundred's digit
8 (the 8 in the middle)is the thousand's digit
0 (the 0 farthest to the right) is the ten-thousand's digit
0 (the 0 farthest to the left) is the hundred-thousand's digit
8 (the 8 on the far left) is the million's digit

Since you are to round off to the nearest ten thousand, I will color
the ten-thousand's digit, the right-most 0, red,
and the digits to the right of it blue:

                  8,008,278
 
We look at the digit just right of that 0.  It is an 8.  Since 8 is 5 or more
we add one to the 0 in the ten-thousand's place, getting 1, so we replace that
0 in the ten-thousand's place by 1.  Then we replace ALL digits to the
right of that ten-thousand's digit with 0's

Final result:
                  8,010,000
