Why are tally marks called tally?

Tally marks are called "tally" because the term originates from the Word "tally," which means to count or keep score. Historically, tallies were used to record counts or amounts, often by making marks on a tally stick or other surfaces. Each set of five marks typically forms a group, making it easier to count larger numbers efficiently. The system remains a simple and effective way to track quantities visually.
