Arrange the digits 0‑9 into a ten-digit number such that the leftmost n digits comprise a number divisible by n. For example, if the number is ABCDEFGHJK, the three-digit number ABC must be divisible by 3, the five-digit number ABCDE must be divisible by 5, "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-1227172931607686978.post-50586615088913984122022-03-02T08:00:00.001-05:002022-03-02T08:00:00.230-05:00Girls' Angle Bulletin....
