Hello...
My name is Abacus , I am a mechanical device used to do mathematical calculations.
Though, I don't remember my exact birth origin, but i was used in the ancient Near East, Europe, China, and Russia, centuries before the adoption of the Hindu-Arabic numeral system.
Sai Intellect Academy, one of the leading training academy in Bangalore, recognized my efficiency and are indulged in training the children about "Abacus and its importance."
