Finger counting
From Wikipedia, the free encyclopedia
Finger counting, or dactylonomy, is the art of counting along one's fingers. Though marginalized in modern societies by the Arabic numeral system, formerly different systems flourished in many cultures, including educated methods far more sophisticated than the one-by-one finger count taught today in preschool education.
Finger counting can also serve as a form of manual communication, particularly in marketplace trading and also in games such as morra.
Finger counting is studied by ethnomathematics.
