The mechanism underlying such unconscious counting is to be found in the plasticity of synaptic connections rather than abacuses or registers, but it constitutes counting nevertheless.
Not as counters on an abacus, or stave, which keeps them too hard and bead-like.
Compared to this positional system, the usual methods of calculating with the abacus seemed to him themselves almost a kind of miscalculation.
An interesting situation occurs when experts of abacus operations perform calculations using either a physical or a mental abacus.
Based on this theory, mental abacus operations correspond to offline, conscious manipulation of an imaginary abacus supported by a modality-specific emulator.
One may speculate whether a culture based on reversible computation like an abacus would have developed a different basic computational model.
The central volutes intertwine and a tendril and foliage breaks the line of the abacus between these and the angle volutes.
Intriguingly, abacus experts not only manipulate the device skillfully but also develop an amazing mental calculation skill after proper training.
In abacus classes, students are taught how to use the tool effectively.
Skilled abacus operators hold running sums of three or four digits while performing mental computation.
They first learn physical abacus operations, and then they train themselves to operate on a mental abacus image, moving their fingers as if they were pushing imaginary abacus beads.
An abacus is a traditional calculation device consisting of a frame, a horizontal dividing bar, and columns of beads, each of which has a place value.
No society in the world has ever proceeded by handing itself over to the abacus men who tell the people how they should proceed.
