The Art and Science of Learning Craft  


Vedic Math's & Other Methods

Vedic mathematics is a system of mathematics consisting of a list of 16 basic sutras, or aphorisms.

They were presented by a Hindu scholar and mathematician, Bharati Krishna Tirthji Maharaj,  during the early part of the 20th century.

The Trachtenberg System is a system of rapid mental calculation, somewhat similar to Vedic maths.

It was developed by the Ukrainian engineer Jakow Trachtenberg, in order to keep his mind occupied while being held in a Nazi concentration camp.

Both the systems despite claims to the contrary, are nothing more than tricks and short cuts involving elementary arithmetic and algebra (in case of Vedic math's).

Further as these are only short cuts,they lack generality of applicability. As these systems only help in arithmetic computations, which only play a small role in mathematics, they do not help much those students who need to master many branches of mathematics. 


Use of Abacus, system of finger binary and its variant Chisanbop, developed by Hang Young Pai, suffer from same limitation.

It is surprising even today there are institutes training students, in using Abacus.

When calculators are available, which are more faster and accurate, why use an Abacus?.

Using a William Oughtred’s Slide rule is more beneficial. With it we can make calculations much faster than  we do with an abacus.

There is no truth in the claim that learning to use Abacus improves sharpness or makes one more intelligent.

For learning these things only increases crystallized intelligence. The learning acumen i.e. Fluid intelligence does not change.
