Using 472 635, each digit drops onto its own strip with zeros after it, showing it is worth 400 000, 70 000, 2000, 600, 30 or 5. The strips are then added like a column addition, which gives 472 635 back and confirms that a digit's place tells you what it is worth.

What is each digit in 472,635 worth?

Each digit has its own place, from hundred thousands down to ones.

The 4 is in the hundred thousands place, so it is worth 400,000.

The zeros keep the 4 in the hundred thousands place.

The 7 is in the ten thousands place, so it is worth 70,000.

The 2 is in the thousands place, so it is worth 2000.

The 6 is in the hundreds place, so it is worth 600.

The 3 is in the tens place, so it is worth 30.

The 5 is in the ones place, so it is worth 5.

Now add the six values together.

The total is 472,635, the number we started with.

A digit's place tells you what it is worth.
