Vedic Multiplication のアプリ分析 12月25日

This math app is about a multiplication technique introduced by Shri Bharti Krishna Tirthaji in his book “Vedic Mathematics”, published in 1965. Tirthaji claimed to have found the mathematical content for his book in ancient sacred Hindu texts. In the vertically and crosswise multiplication method the numbers are multiplied by altering vertical and crosswise multiplications so that two digit numbers can be multiplied in just three steps: vertical, crosswise, and vertical. Three digit multiplications require just five steps: vertical, crosswise, vertical, crosswise, and vertical. The method has similarities with the lattice and grid multiplication methods. With enough practice one can eventually do all the steps in one’s head and mentally solve multiplication problems without writing the steps down.
