How to use a Counting Board Abacus
1-10 of 18A tutorial on how to use a Counting Board Abacus like The Salamis Tablet. NO ADDITION OR MULTIPLICATION TABLES NEEDED! Constrained bead Abaci like the Suan Pan, Soroban, and Roman Hand Abacus are functional subsets of the Salamis Tablet and were developed much later.
