Place Value

Place value “pertains to an understanding that the same numeral represents different amounts depending on which position it is in” (Charlesworth P. & Lind, 2003, pp. 308–309). The place value concept enables us to represent any value using 10 symbols (0–9) and compute using whole numbers.
Other positional or place value systems include those based on groups of 12, as seen in clock time for counting hours, or groups of 60, for minutes in the hour.
