Professor D. O’Phantus does all his calculations in code, with each digit represented by a letter of the alphabet. Each letter always stands for the same digit and each digit is always represented by the same letter. At the end of one of his confusing lectures on “Letter Theory” some examples of calculation remained on the blackboard.
According to the professor:
Sadly, the result of another addition:
had been wiped out, but when it was multiplied by the result of the previous sum it apparently yielded OMTTOUI.
“This is quite hopeless”, said Magnus Swottus. “How can we do lots of lovely homework if we don’t know what the letters stand for? It might as well be Greek.”
But Goody-Goody Major, unwilling to be done out of his homework, was more philosophical. “We’ll just have to crack old Doodah’s code, and then just think of all the problems open to us? We’ll even be able to invent our own!”
Can you help these young enthusiasts by writing out in order the letters corresponding to the digits from 0 to 9?
