Taken from Crossword Extravaganza by Dell: Place numbers on the dashes such that the multiplications are correct. Columns marked with // must contain one occurrence of the digits 1-5. // // // 1. 1 x __ = __ x __ = __ x __ = 60 2. 2 x __ = __ x __ = __ x __ = 12 3. 3 x __ = __ x __ = __ x __ = 45 4. 4 x __ = __ x __ = __ x __ = 32 5. 5 x __ = __ x __ = __ x __ = 200

Shawn, Either you missed something or your rules are a bit vague. First of all, there are 6 slots and only 5 digits. Second of all, if you multiply two two digit numbers, you MUST get a three digit number. Therefore all five of equations are impossible. Marc | |||||

Only columns marked with a // are limited to one occurrence of the digits 1-5. Every other blank space will contain the result of the previous multiplication: // // // 7 x 1 = 7 x 4 = 28 x 3 = 84 -- -- -- -- -- | |||||

Thanks for the clarification, I thought __ meant I needed two digits. Now to work on the problem. Marc | |||||

Solution behind form feed: The part that makes it easy is to take the final result, divide by the first term, and then figure out what three numbers when multiplied together get that result. So, for example, take number 2. The final result is 12, divide that by the 2 at the beginning and you get 6. What three numbers when multiplied together total 6? 1,2,3 1. 3,4,5 2. 1,2,3 3. 1,3,5 4. 1,2,4 5. 2,4,5 Now the trick is to align the columns such that each of the three columns has the numbers 1 - 5. So the solution becomes: 1. 5,4,3 2. 1,3,2 3. 3,1,5 4. 4,2,1 5. 2,5,4 Marc | |||||

Looks good to me. I got the numbers in a different order, but it appears that there is more than one solution. |
