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.
