Re: What do you think?

I have been looking at the sequence of answers for a pattern there.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: What do you think?

New Problem:

Find the smallest natural number for which, if you move its last digit to the beginning, you get a number that is 6 times the original. Or prove that no such number can exist.

A says) Finally some real mathematics, I have a proof using Banach spaces that no such number can exist!

B says)I have the number. It is

C says) Hold on B, how can you have the number after A proved it can not exist? You should not go off making spurious claims. A has done it again.

D says) A has confused me again.

E says) I have the number too but it is larger than B's.

Who is right? Can there be at least 2 solutions or no solutions?

Re: What do you think?

Hi Agnishom;

There are at least two ways, computer and a little algebra. Actually this makes a good Euler project and you should try it by programming first.

Re: What do you think?

It would take too much time for my computer to calculate 50 digits of numbers.

How do I start eliminating possibilities?

Re: What do you think?

Hi;

There is a famous article written by an unknown genius called "Commonsense Brute Force and the Computer," that covers this concept.

Re: What do you think?

smile Why does the genius still wish to remain anonymous???

However, will you please explain the pseudocode to the problem?

I will see what I can come up with.

Re: What do you think?

Hi;

Yes, but believe it or not Mathematica makes those problems very easy. I hardly had to do any coding at all!
