    cute.
    but Natalie, it’s no magic… it works in other bases too
    in octal:
    1*6 + 1 = 7
    12 * 6 + 2 = 76
    123 * 6 + 3 = 765
    1234 * 6 + 4 = 7654

    1234567 * 6 + 7 = 7654321

    and in hexadecimal
    123456789abcdef * e + f = fedcba987654321

    see if you can figure out why though
