What is Mental Arithmetic?

Mental Arithmetic is a tested way of developing a child’s academic abilities and creative thinking in a balanced way, allowing them to reach their full intellectual potential.

At the beginning of the course, an abacus is used for children to learn the techniques. Later, children learn to do calculations in their head by forming a mental image of a number on the abacus and can do all mathematical operations (addition, subtraction, multiplication, and division) with any numbers in mind.
