Decimals extend the bundles
After the ones, each seat is a ten-times smaller piece.
Why this exists
A whole meter, a whole dollar, a whole kilogram — sometimes one unit is too blunt. You split one into ten equal parts and want to write that with the digits you already know.
Decimals don’t add new digits. They add new seats, to the right of the ones, for pieces.
