Vedic Maths - Tutorial 2 <http://vedicmaths.110mb.com/tutorial2.html>
Using VERTICALLY AND CROSSWISE you do not need to the multiplication tables beyond 5 X 5. - Suppose you need *8 x 7* 8 is 2 below 10 and 7 is 3 below 10. Think of it like this: The answer is 56. The diagram below shows how you get it. You subtract crosswise 8-3 or 7 - 2 to get 5, the first figure of the answer. And you multiply vertically: 2 x 3 to get 6, the last figure of the answer. *That's all you do:* See how far the numbers are below 10, subtract one number's deficiency from the other number, and multiply the deficiencies together. - *7 x 6 = 42* Here there is a carry: the 1 in the 12 goes over to make 3 into 4. ------------------------------ Here's how to use VERTICALLY AND CROSSWISE for multiplying numbers close to 100. - Suppose you want to *multiply 88 by 98*. Not easy,you might think. But with VERTICALLY AND CROSSWISE you can give the answer immediately, using the same method as above. Both 88 and 98 are close to 100. 88 is 12 below 100 and 98 is 2 below 100. You can imagine the sum set out like this: As before the *86* comes from subtracting crosswise: 88 - 2 = 86 (or 98 - 12 = 86: you can subtract either way, you will always get the same answer). And the *24* in the answer is just 12 x 2: you multiply vertically. So *88 x 98 = 8624* http://vedicmaths.110mb.com/tutorial2.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "AJAX_Tools" group.
