Re: correct formula

That's the formula in post #14 by Relentless.

Re: correct formula

Also, how is it any more valid a solution than the original one of post #2...

Just generated 835 more such formulas in addition to the 2 we stated in excel in the hopes of finding something easy to convert to a form with "no repetition", as well. I don't know what's more painful; the problem, or the comprehension skills of those promoting it.

Re: correct formula

Equally painful! I wonder what the 'correct' answer is.

835 solutions! Getting close to "infinitely many"!

Re: correct formula

Sorry, 837. That should be the number of valid solutions with the first digit multiplied only by 1 (I forgot) and the others multiplied by positive integers from 1 to 10. Infinite solutions are for when you extend to any coefficients satisfying post #3's terms. And that's just a small part of the range of answers with very restricted boundaries, within one fixed application of operations (multiplying by coefficients and summing).

Cannot speak for answers with no repetition or reordering and +,*,() only, though.

Re: correct formula

Oh my god... The 'correct' solution is a picture of some excel cells exactly as given in post #25. And when oranghijau posted your answer.... which, by a stroke of luck, exactly corresponds to the products in those cells expanded to addition/subtraction... it is greeted with scrutiny, the admonition to not overcomplicate things and keep it simple stupid, a restatement of the now unmasked rubbish condition to only use the digits once (which is based on lacking the imagination to convert between addition and multiplication), and the final admission that even though the answer differs from the original one (which, even if that were an excuse, is totally false), it appears to work
