From New Scientist #1175, 4th October 1979 [link]
Letters stand for digits, but who knows what stands for what?
You’ve got to use your wits and thus decide.
Different letters, different digits, for I’ve got,
As maker of the puzzle, proper pride.
E and R and I and C, that makes a name,
And the second line is similar,
With 2 letters familiar
For E and R, read I and P, and then the same.
With an R and a V and a couple of E‘s,
The sum is completed, but please
Do you add or subtract? That’s for you to discover
If the one can’t be done, then it must be the other.
Do you add or subtract? Write the sum out with the numbers substituted for letters.
This is the 300th Enigma puzzle posted to the site (that’s 17.3% of all Enigmas published).
