Learning abacus makes you understand the concept of numbers and improves your mental arithmetic skills and basic arithmetic ability in a short period of time. Basically, math is limited to the area of the left brain responsible for logic languages. However, abacus arithmetic stimulates the visual, auditory and tactile without exception and actively helps the development of the right brain responsible for the artistic and sensory abilities as well as the left brain. 
This course covers basic operations like addition and subtraction using an abacus and makes you calculate easy, correct and fast.

  • Can learn abacus not boring with multimedia, graphics, subtitles, the motion of the character.
  • Can calculate arithmetic operation easily and fun through the decomposition and combination of number.
  • Adds a number and factor of an abacus to the animation of friends anthropomorphic abacus bead, stimulates curiosity and interest and approaches to learning with fun without resistance.
  • Adds interest in math with animated storytelling.
  • In parables and examples related to the number, it improves greatly mental arithmetic skills, calculation ability, logicality and thinking skills.
  • The best means for learning the scientific understanding of mathematical concepts can be utilized for the abacus.

Learn Addition and Subtraction using an Abacus
The entire course leads you through the learning process step by step with multimedia teaching method of the new concept of combining unique character, animation and story telling and makes you study with ease and a lot of fun.
It contains a number of tutorials, which are fundamental for you.
There are many benefits to learning abacus calculation. You can have concentration, patience and sense in number including by working with the abacus and the brain develops while you enjoy the abacus. You can do the sum in your head without a calculator in mathematics.
Also, anyone who wants to strengthen their understanding of abacus or anyone who wishes to learn from scratch or teach it can benefit from this course.
A learning method that is very effective in improving the concentration that is scarce in the digital age (PC, mobile game) and developing brain such as mathematical thinking ability and creativity.
