From proverbs to alphametics (Posted on 2013-02-15) Difficulty: 4 of 5
The proverbs:

The early bird catches the W1.
Where the wolf gets one W2 - he looks for another.
The best horse doesn't always win the W3 .
Better wed over the mixen than over the W4.

The alphametics:

W3+W2=W1
W3-W2=W4

The phrase "The bear came home to the wolf" uses 12 distinct letters, - three of them were not used in the alphametics.

Which three?
What digit was not used in the equations?

Check this out first: http:  //members.iinet.net.au  /~brianjnow  /perplexus  /Perplexians.html (delete all spaces)

Following advice the program listing was adjusted and then a few minor utility lines were added to give this print-out:

W1 worm 8915
W2 lamb  7453
W3 race  1462
W4 moor 5991
