Counting rods are a historical counting tool used in ancient civilizations, particularly in China, to perform arithmetic operations and keep track of numbers. They consist of a series of rods, typically made of bamboo or other materials, that were used in conjunction with a counting board or surface marked with specific lines or grids. The counting rods allowed users to represent numbers in a visual and tactile manner.
