Vedic Maths is series of mathematical tricks, originating in a book written by an Indian monk Swami Bharati Krishna Tirtha in 1965. It contained a list of mental calculation techniques which were claimed to be retrieved from the Vedas - are a large body of religious texts originating in ancient India.
Please if you are learning this, however, do not treat multiplication as a mere trick. It is important to remember 17 x 13 for example, is the repeated adding of 17, 13 times (17 + 17 + 17 + 17...).
This method is a shortcut, but as the end proof shows, it is using a shuffling of required calculations to make this multiplication more efficient.
For 17 x 13, we have lots of multiplication going on (that is repeated addition!) - 10 x 10 and 3 x 10 and 7 x 10 (lots of 10s - 20 all up) - and 7 x 3.
