... Solution: In the product the first digit is one less than the second factor, and the last digit is 10 minus the second factor. In other words: For 999,999 × 1, first digit: 1 – 1 = 0, last digit: 10 – 1 = 9 For 999,999 × 2, first digit: 2 – 1 = 1, last digit: 10 – 2 = 8 For 999,999 × 3, first digit: ...

Error Detection Using Check Digits
... The final character of a ten digit International Standard Book Number is a check digit computed so that multiplying each digit by its position in the number (counting from the right) and taking the sum of these products modulo 11 is 0. The furthest digit to the right (which is multiplied by 1) is th ...

... Problem 2. For an integer t, we define s(t) to be the sum of digits of the binary form of t. [For example, s(13) = 1 + 1 + 0 + 1 = 3 as 13 = 11012 in binary.] Find the sum s(0) + s(1) + s(2) + . . . + s(511) (in decimal). Problem 3. Find the number of ways to put n indistinguishable balls into k bin ...
