Place Value

Pick a value to view its full reference table.

Place values up to 10. Each place is ten times the place to its right — this is the core of our base-10 number system.

Position is power in base ten: a digit’s worth depends on where it sits, tenfold at every step left. Ones, tens, hundreds, thousands — each place is the previous one times ten, and 10,000 reads as a single 1 backed by four empty zeros. The chart absorbs any size: millions, billions, trillions simply repeat the ones-tens-hundreds trio under new group names. Other bases, binary or dozenal, work the same way with a different step. Commas group digits in threes to keep large numbers readable.
