It is a high-level cognitive skill that runs through calculations with an effective algorithm.
People doing long-term AMC training show higher numerical memory capacity and have more
effectively connected neural pathways. It results in higher nodal degrees in bilateral calcarine
sulcus and increased local efficiency in bilateral superior occipital gyrus and right cuneus. The
AMC group also showed higher nodal local efficiency in right fusiform gyrus, which was
associated with better math ability. Long-term AMC training may improve information
processing efficiency in visual-spatial related regions. Children with abacus training had
significantly better reaction time and scores than children without abacus training. Long-term
AMC training improves auditory abilities in children
