A note on the name
“Vedic Mathematics” is a modern collection of calculation methods popularised by Bharati Krishna Tirthaji. His claim that the sutras came from the Vedas is disputed by historians. The methods are worth exploring on their mathematical merits.

What is “Vedic Mathematics”?
The name is commonly used for a collection of arithmetic and algebraic methods associated with Bharati Krishna Tirthaji’s Vedic Mathematics, published in 1965. His book presents 16 sutras and associated methods. Some of the techniques also appear elsewhere in mathematical traditions.
Tirthaji attributed the sutras to the Vedas. Historians and mathematicians have challenged that attribution; it should not be treated as an established historical fact. The mathematical validity of a method can be checked independently of its origin.
Scope
This lab teaches a broad selection of practical techniques associated with the tradition and related mental arithmetic. It is not a complete catalogue of every sutra, sub-sutra, or possible application. The labels describe techniques; they do not claim a one-to-one mapping to all sutras. Practice is designed around the stated conditions of each method.
