Definition
Ones place
The ones place is the position where each unit is worth exactly one.
What it means
Base-ten numbers group units by place. The ones place holds the leftover single units after tens, hundreds, and larger groups are counted. In 482, the 2 means two ones.
Remember it
The ones place is the single-unit seat, just left of the decimal point.
Example
In 7,306, the digit 6 is in the ones place, so it contributes 6 to the number.
Watch for
The ones digit is the digit sitting there; the ones place is the position itself.
Common mix-up
The ones place is not always the last printed digit: in 24.7, the 4 is in the ones place.
Exact meaning
In a base-ten numeral, the ones place is the digit position immediately left of the decimal point; its digit counts single units.
