Effectiveness of Vinculum in Fast Multiplication

‘Vinculum’ is an important term in Vedic mathematics. Calculations are made simpler by converting digits larger than five into their complementary values below five. By decreasing the possibility of carry-overs, this reduction speeds up and improves the efficiency of mathematical operations. Long multiplication, also known as column multiplication, is a method for multiplying numbers especially those with multiple digits by breaking down the process into small manageable steps. This paper includes action research on the group of 20 students of class 7 & class 8. This study is based on the use of vinculum method to do long multiplication problems. Vedic method based on vinculum and Nikhilaṃ Navataś charamaṃ Daśataḥ sutra (all from 9 last from 10) and Ekādhikena Pūrveṇa sutra (One more than the previous one) is used by these students for enhancing the mental capability and reducing the time duration during the session.The main components of the paper are accuracy and fast calculation.
