DescriptionTraditional Chinese abacus illustrating the suspended bead use.jpg
English: Using traditional multiplication and division techniques requires that some of the rods of the abacus temporarily hold values as high as 19, which would require the presence of three beads on top. With only two upper beads, the third can be simulated or coded using the "suspended bead". The image shows values from 8 on the left to 20 on the right. Note the use of the suspended bead on the five rightmost rods.
Español: El uso de técnicas tradicionales de multiplicación y división requiere que algunas de las varillas del ábaco mantengan temporalmente valores tan altos como 19, lo que requeriría la presencia de tres cuentas en la parte superior. Con solo dos cuentas superiores, la tercera se puede simular o codificar utilizando la "cuenta suspendida". La imagen muestra valores desde 8 a la izquierda hasta 20 a la derecha. Nótese el uso de la cuenta suspendida en las cinco varillas de la derecha.
