Re: Nohow

Only the numbers on the left are in the 5-digit NOHOW form of _0_0_, and when on the right they are in the 3-digit NHW form of _ _ _.

That occurs, for example, with n in clues 9 and 11.

Sorry, have to disappear for an hour or so...

Re: Nohow

So if I solved #11 first and got n = 10201( hypothetical only ) and then used it in 9, I would then use n = 121? See you then, I have one more question.

Re: Nohow

Supposing I came up with an answer that was 90903 for the LHS of a clue. It factors to {3, 1}, {157, 1}, {193, 1}. So you see it has the two required 3 digit prime factors but it also has a smaller one. Is this legal?

Re: Nohow

No, that's not legal.

...this number is equal to the product of two 3-digit primes

90903 is not the product of two 3-digit primes: it is a single-digit prime x the product of two 3-digit primes.

Okay, thanks for the clarification. I will work on it again.

Ok...good luck with it.

I'll be up for a while watching the French Open, so if you need more clarification just let me know.

Re: Nohow

Hi Bobby;

I added...

Couldn't do it all with M, though...some human input required during the solving process.

...to post #70.

I tried, but I just couldn't get M to solve the whole bang lot...it needed my help. It's so nice to be needed! smile

Re: Nohow

That's good news about the progress. smile

When you're done solving, I'll need your help to iron out an annoying coding quirk with this puzzle that I can't figure out. I've got a workaround for it, but it's making my code look awkward.

Re: Nohow

Same here...just tidying up code (except for the quirk I mentioned, that seems to defy logic and to which I don't have the answer).

Also, I've started on an M code version that's less LB-/Excel-like, but am struggling.

Re: Nohow

At this point, I have solved all the equations but have several answers for each one. I am attempting to prune each down to 1 answer.

Re: Nohow

Well, I only saw it after I'd already solved the puzzle (yonks ago), and I immediately updated my strategy. All I can say is...it's worth finding! smile

Hi;

Are all the 5 digit numbers different? Are all the 3 digit ones different?

Re: Nohow

Hi Bobby,

For the 3-digit numbers, do you mean only those that are of the NHW form?

What I mean there is that the puzzle grid contains 24 answers, all of which are 3-digit numbers...but only a few of those are of the NHW form.

Assuming you're referring only to NHW numbers,  the answer is in the hide box:

Re: Nohow

Ah, good.

Btw, a couple of days ago I found an M function that does the task of two functions in my code, and I also discovered a trick by which I was able to neaten and shorten my code. It looks much more ordered now, and is also much shorter than my original version. smile

Mine grows longer and uglier by the day but the rule of EM is; answer first, then code. Same for math, answer first, then math.

Re: Nohow

Same for chess:

Your NOHOW solution is correct. Excellent! smile

Now all you have to do is to think back to how you did it, and then tell me. I suspect you didn't just pluck numbers out of the air, as you were leading me to believe. wink

I'll PM you my M file, but I have to disappear for an hour or so first.

Oh yes...you didn't show your answer for the check.

And what did you think of the puzzle?
