Abacus: Definition and Function
An abacus is a manual calculating tool with beads on rods used for arithmetic.
The abacus is an early calculating device consisting of a frame with rods or wires, each holding beads representing numerical values based on their position. Users manipulate the beads to perform arithmetic operations like addition, subtraction, multiplication, and division.

🧒 Explain Like I'm 5
It's like a frame with rows of beads. Each row is for a different place value (like ones, tens). You slide the beads to count and do math.
🤓 Expert Deep Dive
The abacus operates as a physical, analog computing device employing a positional numeral system. Beads are moved on rods, each representing a digit's place value. Calculations are performed by physically arranging beads to represent numbers and applying algorithms for arithmetic operations. Its effectiveness relies on user proficiency in translating bead positions into numerical values and executing calculation steps.
