The multiplicatiou of 987,654,321 by 45 is 44,444,444.445. Reversing the order of the digits, and multiplying 123,456,789 by 45, we get the result equally curious, 5,555,555,505. If we take 123,456,789 as the multiplicand, and, interchanging the figures" of 45, take 54 as the multiplier, we obtain another reinarkable product, 6,666,666,606. Returning to the mnltiplioand first used, 987,654,321, and taking 54 as multiplier again, we get 53,333,333,334 - all threes, except the first and last figures, whioh read together 54, the multiplier. Taking the same multiplicand and using 27, the half of 54, as the multiplier, we get a product of 26,666,666,667- all sixes except the first and last figures, whioh read together 27, the multiplier. Next, interchanging the figures in the number 27, and using 72 as the multiplier, with 987,654,321 as the multiplicand, we obtain the product of 71,111,111,112, all ones, except the first and last figures, which, read together, give 72, the multiplier. Equally curious results may be obtained by multiplying these digits, written either way, by 9, or by the figures composing the mĂșltiples of 9 variously interchanged.
