VEDIC MATHEMATICSINTRODUCTIONVedic Mathematicsis a book written by the high-ranking Hindu clericBharati Krishna Tirthajiand first published in 1965. It contains a list ofmental calculationtechniques claimed to be based on theVedas. The mental calculation system mentioned in the book is also known by the same name or as "Vedic Maths". Its characterization as "Vedic" mathematics has been criticized by academics, who have also opposed its inclusion in the Indian school curriculum.PUBLICATION HISTORY Although the book was first published in 1965, Tirthaji had been propagating the techniques since much earlier, through lectures and classes.He wrote the book in 1957 during his tour of the United States.The typescripts was returned to India in 1960 after his death. It was published in 1965, five years after his death as 367 pages in 40 chapters. Reprints were made in 1975 and 1978 with fewer typographical errors.Several reprints have been made since the 1990s. Tirthaji claimed that he found the sutras after years of studying theVedas, a set of sacred ancient Hindu texts.However, Vedas do not contain any of the "Vedic mathematics" sutras.First, Tirthajis description of the mathematics as Vedic is most commonly criticised on the basis that, thus far, none of the stras can be found in any extant Vedic literature (Williams, 2000). When challenged by Professor K.S. Shukla to point out the sutras in question in theParishishtaof theAtharvaveda, Shukla reported that the Tirthaji said that the sixteen sutras were not in the standard editions of the Parishishta, and that they occurred in his own Parishishta and not any other. CONTENTS The book contains 16sutras, each of which lists a mental calculation technique. Prof.S. G. DaniofIIT Bombaypoints out that the contents of the book have "practically nothing in common" with the mathematics of the Vedic period or even the subsequentIndian mathematics. Tirthaji has liberally interpreted three-word Sanskrit phrases to associate them with arithmetic. The sutras are as follows:

The first edition of the book edited by Prof. Vasudeva Saran Agrawala, who indicates that there is no evidence that the sutras are "Vedic" in their origin.The techniques mentioned in the book do not date back to the Vedic period either. For example, multiple techniques in the book involve the use of decimal fractions, which were not known during the Vedic times: even the works of later mathematicians such asAryabhata,BrahmaguptaandBhaskarado not contain any decimal fractions. Tirthaji's claimed that the sutras are relevant to advanced mathematical techniques such as successive differentiation or analytical conics have also been dismissed by the academics. S. G. Dani calls "ludicrous" the Tirthaji's claim that "there is no part of mathematics, pure or applied, which is beyond their jurisdiction".S. G. Dani also points out that Tirthaji's methods were not unique, although they may have been invented by him independently (he held an MA in mathematics). Similar systems include theTrachtenberg systemor the techniques mentioned in Lester Meyers's 1947 bookHigh-speed Mathematics.Alex Bellospoints out that several of the calculation tricks can also be found inearly ModernEuropean treatises on calculation. Use in schools: The book was previously included in the school syllabus ofMadhya PradeshandUttar Pradesh.[3]:6Some schools and organizations run byHindu nationalistgroups, including those outside India, have also included Tirthaji's techniques in their curriculum. The Hindu nationalists have also made several attempts to have Tirthaji's "Vedic mathematics" system included in the Indian school curriculum via theNCERTbooks. A number of academics and mathematicians have opposed these attempts on the basis that the techniques mentioned in the book are simply arithmetic tricks, and not mathematics. They also pointed out that the term "Vedic" mathematics is incorrect, and there are other texts that can be used to teach a correct account of theIndian mathematicsduring the Vedic period. They also criticized the move as asaffronizationattempt to promote religiousmajoritarianism. Dani points out that while Tirthaji's system could be used as a teaching aid, there was a need to prevent the use of "public money and energy on its propagation, beyond the limited extent". He pointed out that the authentic Vedic studies had been neglected in India even as Tirthaji's system received support from several Government and private agencies. Vedic mathematics is now taught by several schools and organisations in India as well as other parts of the world. The Chinmaya International Foundation, a foundation of the Chinmaya Mission, is among the proponents of the Vedic Mathematics system.
