Abacus, an ancient invented tool which evolved with time and today discovered as an educational device of new age education for children to learn the skill of visualisation of mathematical calculations through the references of beads on Abacus.
A methodology which challenges the brain to "concentrate and focus", "listen and process information", " image, visualise and memorise" enabling brain to skill for life be perseverant, creative, lead, vision, foresight, plan execute and much more.
THEORY; Abacus is an ancient calculating device having its roots in Asia since ages. Abacus in today's times time is made of wood, metal or plastic rectangular frame with freely sliding 5 beads over vertical rods. These beads are parted by a at-least fixed horizontal bar where 1 bead over the vertical bar is placed above the fixed horizontal bar and the remaining 4 beads below the fixed horizontal bar. The beads above the fixed horizontal bar represent number 5 whereas other each of the 4 beads below represent number 1.
Any bead which moves towards the fixed horizontal bar gains value and when it moves away from the fixed horizontal bar losses value, which can be interpreted as 1 bead below the fixed horizontal bar moving towards thefixed horizontal bar means 1 on abacus and 4 beadsbelow the fixed horizontal bar moving towards thefixed horizontal bar means 4 and so as the case with1 bead above the fixed horizontal bar moving towards thefixed horizontal bar means 5. moving away from the fixed horizontal bar is -1, -4 or -5 as the number of beads may be. Vertical rods on Abacus are used to represent the place value of number. If the centre rod of Abacus is place of One's or Unit, the immediate next rod to the left is theplace of Ten's and the immediate nest rod to the left of Ten's is Hundred's and so on and so forth for thousand, 100 Thousand, Million's etc. Learning the skills to operate Abacus can easily enable a person to perform Arithmetic Operations of Addition, Subtraction, Multiplication, Division, Square Roots, Cube Roots etc. with ease after practicing the methods. In the today’s time children love learning this tool and through guided Abacus Training they even can imagine abacus in their photographic mental ability to perform rigid calculations even faster than anyone attempting it on a calculators or computer.
This ancient tool of calculation has now become a Supplementary Education to strengthen children's skills for Fast and Accurate Math ability with enhancing and polishing the brain functions like Concentration, Focus, Listening, Analysing, Comprehending, Imagination, Retention, Memory, Perseverance, Creative Intelligence etc. So the modern definition of abacus is changed to, ' A math tool for brain exercise"
