|I bought this abacus in San Francisco's China Town while on a family vacation
during the summer before 4th grade. By the time we got home I knew how to use
it to add, subtract, multiply and divide.
This is a Chinese style abacus called a suanpan. The Japanese style, called a
soroban, only has 1 bead on the top and 4 on the bottom.
