SUMMARY

The discussion revolves around a long multiplication puzzle where each 'U' represents a unique decimal digit from 0 to 9, with the stipulation that each digit must appear exactly twice in the multiplication. The initial confusion stemmed from the assumption that the same digit could be used for all 'U's, which is incorrect. The corrected problem statement clarifies that the digits must be distinct and fulfill the specified conditions, making the puzzle solvable under these constraints.

PREREQUISITES
  • Understanding of basic multiplication concepts
  • Familiarity with decimal digits and their properties

In the following long multiplication puzzle, each of the U’s represents a decimal digit from 0 to 9, whether same or different.

Each digit from 0-9 must appear precisely 2 times in the following multiplication.

None of the numbers can contain any leading zero.


...U U U
...U U U
-----------
...U U U
...U U U
U U U
------------------
U U U U U

Determine the multiplier, multiplicand and the product.

Note: The dots are present merely for the sake of formatting, and none of the dots represent a decimal point.

I don't follow. Why couldn't the answer be:

111 * 111 = 12321
or
111 * 222 = 24642
or
123 * 321 = 39483
etc.

Clearly if all the U's represent the SAME digit, the puzzle is impossible, unless U=0. And if U's are different digits, there are seemingly a plethora of answers, so long as each digit in the 2nd number times the 1st number is smaller than 1000, and obviously the product is less than 100000. What am I missing?

You’re right, davee123.

I really goofed up the problem statement and forgot to add that:

”Each digit from 0-9 must appear precisely 2 times in the following multiplication.”

I have now incorporated the said amendments in the problem text.

I sincerely apologize for the inconvenience caused due to the foregoing.
