What is Mental Math?
Mental math is the essential building block that replaces the physical Abacus in the child’s mind. As the children gradually learn to visualise the Abacus in their mind (virtual Abacus), they learn to calculate mathematical problems using the principles of the Abacus, without the use of the physical tool.
