    Mod 7 test in base 1000

    Show that: A number N is congruent modulo 7 to the alternating sum of its digits in base 1000 (for example, 123456789 = 789 - 456 + 123 = 456 mod 7) So... here's what I have (not much). Say the digits of N are dn ... d2 d1 d0, where each d is a digit that varies from 0 - 999 (using those as...
