Vedic mathematics is a list of sixteen basic sūtras, or aphorisms, presented by a Hindu scholar and mathematician, Bharati Krishna Tirthaji Maharaja, during the early part of the 20th century. While its author claimed it to be a system of mathematics, this is not generally accepted, and it is more generally regarded as a set of strategies for calculation. These are said to be creative and useful, and can be applied in a number of ways to calculation methods in arithmetic and algebra, most notably within the education system. Some of its methods share similarities with the Trachtenberg system.
