I came looking for this topic to find the thing that ganesh said about the nth root of n that I knew that he'd said but I'd forgotten what it was that he'd said, so that I could quote him on it here.

While I was reading through the topic, I noticed the thing about splitting a number into parts to get a maximum product and I had a really nit-picky idea.

Using MathsIsFun's 15 as an example, you could technically have (-10)*(-10)*35 = 3500, or anything involving 2 negatives like that, to get a much bigger product. It's completely cheating though.

I probably don't understand what ad-finum means, but I noticed in the original subject covered before angel and candy,  that the sequence of powers is parenthesized from right to left, that is why most people are confused.  If you do the power and make it the base of the next operation, then it should go to infinity, but I see from your examples that you make the answer the power of the next iteration.  Very interesting.  Bye.

Reminds me of the guy who hires out boats. He yells out "Time is up No 6, please come back ... (pause) ... No 6, time is up!! ... (pause) ... ummm...are you in trouble No 9?"

LOL!!!! That is a very good idea!

Those two are really the same thing, it's just that one of the numbers is written upside-down!

I thought, ganesh, you said there was only one solution to the problem.....was that right?

One die, two dice.
The second die could also be marked 0,1,2,6,7,8.

Mathsy is right! This is a puzzle and crept into 'Help me' by mistake.
Anyway, I shall give the solution.
One dice is marked 0,1,2,3,4,5.
The other is marked 0,1,2,7,8,9.
Don't ask me how you get 6!

I've always been confused on this. Is it one di, two dice; or one dice, two di?

I suspect this puzzle should be solved in the same way as the scales one was.

That's very close, actually. You just need to change one number on one of the dice.

I'm guessing this is a puzzle, rather than a 'help me', so I'll leave it alone.

Nevermind getting a silly combination like 38,
but how would you display, say 22, 23, 24 or 25???
