rounding a four digit number to nearest ten thousand

Question

How do I round 1,996 to the nearest ten thousand?

Answer 1

The 0's at the front can be there, but we almost never write them or use them.  4 is the same thing as 0000000000004.  1,996 is the same thing as 01,996.

We're trying to round 01,996 to the nearest ten thousand.

The 0 is in the ten thousands place.  The next digit over is 1, which is less than 5, so the 0 doesn't round up.

Answer:  00,000 or just 0.
