New Scientist Enigma 1000 – One Thousand Times
by Richard England
From Issue #2155, 10th October 1998
Since M is the Roman numeral for 1000, we can say that with this puzzle New Scientist has published its Enigma M times – which is significant because:
ENIGMA ÷ M = TIMES
In this problem each letter stands for a different digit, and the same letter represents the same digit wherever it appears. No number starts with a zero.
