Counting rods (traditional Chinese: ็ฑ; simplified Chinese: ็ญน; pinyin: chรณu; Japanese: ็ฎๆจ; rลmaji: sangi; Korean: sangaji) are small bars, typically 3โ14 cm long, that were used by mathematicians for calculation in ancient East Asia. They are placed either horizontally or vertically to represent any integer or rational number.
The written forms based on them are called rod numerals. https://en.wikipedia.org/wiki/Counting_Rod_Numerals |
