April 1–April 7, 2008

Problem

Consider the following cryptarithm:

  APRIL
- FOOLS
  -----
    DAY

Each letter A, P, R, I, L, F, O, S, D, and Y stands for a different digit (0-9). After solving the cryptarithm, let UVW = |DAY - YAD| (so UVW is some 3-digit number, letting U and V be leading 0's, if necessary). Here's the problem: what is UVW + WVU?

Solution
