Secondary: Chinese Abacus

ArushaTimes News

Our junior Mandarin students have been making their own Chinese abacus and learning how to use it. The Chinese abacus was first described in Chinese literature in the Eastern Han Dynasty in 190 AD. It can be used for addition, subtraction, multiplication, division, and even in square root and cube root operations. Mrs. Carol Lam, Teacher (Photos by Michael C. and Ms. Lam)
