This amazing quiz can predict which of 17 movies you would enjoy the most..

I don't know how it works, but it does. Play fair, and do the math first before you look at the list:

1. Pick a number from 1-9.

2. Multiply by 3.

3. Add 3.

4. Multiply by 3 again.

5.. Now add the two digits of your answer together.

Scroll down to find your favorite movie in the list of 17 movies below and prepare to be amazed:

The Movies

1. Gone With the Wind

2. The Sound of Music.

3. Blazing Saddles

Let x be the digit you chose.

Let's follow the listed instructions: x -> 3x -> 3x+3 -> 3*(3x+3) = 9x+9 = 9*(x+1) meaning the number you got is divisible by 9.

You may remember from elementary school that any number that's divisible by 9, the sum of its digits is also divisible by 9.
Let's prove this too:
Let a and b be the two digits of our number and n be an integer which is the result of the division. So, (10a+b)/9 = n ,
(10a+b) = (9a+a+b)/9 = (9a/9)+[(a+b)/9] = a+[(a+b)/9] = n.
a is a digit and therefore an integer, meaning (a+b)/9 has to be an integer as well for (10a+b)/9 = n to be true.
This means that a+b is divisible by 9. QED.

Back to our original task:
Since you'll never get 99 (digit sum of 18) by following these steps (highest is 90), the only possible sum of digits you could get is 9.

There's probably an easier way to do this, but meh...

You may want to point out to pick an integer, rather than any number between 1 and 9.

If and when #9 comes out, it may very well be my favorite movie of all time.
... OK, maybe just behind Robin Hood: Men In Tights.

My favorite movies of all time is “Seven Samurai”, which is on the list. And yet my least favorite movie, “The Sound of Music”, came up the winner.

Hi Robert,
How are you?

'The Seven Samurai' is one of my favorites too.

But I think you may have missed one of the math steps if you came up with that result. Try again. You should come up with number 9.

Too, too funny! I was certain that my favorite movie would not be on the list. When I saw my 'answer' #9, I LOL'd and had to admit that would be my favorite movie of all time.

Then without reasoning it out, I intuited that the 'answer' would always be #9 no matter what # was first chosen.
