Introduction to Simple Mathematical Formulae by Bhārati Kṛṣṇa Tīrtha

These are the Sūtras developed by Jagadguru Swami Śrī Bhārati Kṛṣṇa Tīrthaji Mahārāja between 1911 and 1918.

Swamiji was the Shankarāchārya of the Govardhan Math, Jagannath Puri as well as Dwaraka, Gujarat (1884-1960).

Swamiji had developed set of sixteen mathematical formulae or sūtras and their sub sūtras. These single line sūtras are in Samskrita easy to understand and remember. Each sūtra can be applied to solve many different mathematical operations.

These Sūtras help to solve the  'difficult" problems or huge sums  very quickly and calculations can be carried out mentally or involve one or two steps.
