The method of an abacus has been used for hundreds of years and is the symbol of wisdom in numbers. Learning to read numbers on an abacus really does open up a whole new world to explore! The physical movement of the abacus beads will imprint a mental abacus inside your mind, which will allow you to mentally exercise your mind. By stimulating, abacus can help your brain in concentration, observation, memory, comprehension, logical thinking, critical thinking, problem solving, fast judgment, endurance, determination, confidence and the general interest in numbers.
