place value
This term is a technical mathematical concept used primarily in primary education to explain the decimal system. It describes the relationship between a digit's position and its actual worth, distinguishing the face value of a digit from its positional value.
Because it refers to a specific mathematical property, it is treated as an uncountable concept in most pedagogical contexts. You do not typically refer to multiple place values in a way that requires a plural form, but rather discuss the place value of a specific digit.
