We thenmultiply 648 by the 9, and by the 7, shifting the product eachtime one place to the left because the 9 is really 90, and the 7 is700. The three products are then added to make our completeanswer, 513,864. This sounds very elementary. True, but there is a purpose 318 THE CREIGHTON CHRONICLE 6 4- B 7 9 3 13 4-4 5 8 3 8 4 S 3 e 5 I 3 0 B 4 7 9 3B 4 B 4 5 3 G S 8 3 S19 4 4 5 1 3 8 B 4. 2 4 8 4 O f 1 o a o 8 B O O O 4 B o o o a 5 1 3 8 B 4 8 X K ye A ye ^ ?/ /z X 5 5 6 in it. There is no erasing and no writing of unnecessary there is headwork, and that is f atig-uing. Our method is themost practical with Arabic numbers. And there is no intentionon the part of the writer to try and induce the reader to changeit. But our X-)resent method is not and was not the only one everused, nor is it the best in every particular. The Hindus differed from us in two things—they exchangedour positions of the multiplicand and multiplier, and they be-gan at the left. To multiply 648 by 793, they wrote the 793 abovethe 648. See number 2 in the fig-ure. Beginning at the left, theysaid 7 times 6 is 42, and wrote down the 42. Then 7 times 4 is 28,writing down the 8, and adding the 2 to the 2 of the 42, getting44, or 448 so far, by erasing the 2 of the 42 and writing the 4 inits place.
