Place Value
Definition
In the base ten number system, each place has ten times the value of the place to its right.
Example
In the number 1329:
- the one is in the thousands position
- the three is in the hundreds position
- the two is in the tens position
- the nine is in the ones position.
More on Place Value
Large whole numbers are arranged in groups of threes called periods. Each period has a hundred(s), ten(s) and one(s) position.
See the number 123 456 789 below as an example. The 8 is in the tens position, the 5 is in the ten-thousands position.
Decimal numbers are also arranged in groups of threes called periods. Each period has a ten(th), hundred(th) and thousand(th) position.
See the number 0.123 456 789 below as an example. The 2 is in the hundredths position, the 5 is in the hundred-millionths position.
