WHO IS YOUR ROLE MODEL???
Try it without looking at the answers......
please don't look down until you do it, you'll love it I promise
GET A CALCULATOR (YOUR COMPUTER HAS ONE ON IT)
1) Pick your favorite number between 1-9
2) Multiply by 3 then
3) Add 3, then again Multiply by 3 (I'll wait while you get the
calculator....)
4) You'll get a 2 digit number....
5) Add the digits together
Now Scroll down ..............














Now with that number see who your ROLE MODEL is from the list below:
1. Einstein
2. Nelson Mandela
3. Idi Amin
4. Helen Keller
5. Bill Gates
6. Gandhi
7. Paris Hilton
8. Thomas Edison
9. BobG
10. Abraham Lincoln

It's you! :rofl:

I never understood why adding all digits from "9(x) - x any positive number" gives 9

10y+z = 9x (x being 0 to 11)

y+z = Ans
10y+z = Ans+9y

Ans+9y = 9x
Ans = 9(x-y)


.................
makes sense x-y = 1

step1 1 2 3 4 5 6 7 8 9
step2 3 6 9 12 15 18 21 24 27
step3 6 9 12 15 18 21 24 27 30
step4 18 27 36 45 54 63 72 81 90
step5 9 9 9 9 9 9 9 9 9

Algorithm was designed to result 9 regardless of first number.

Who would need a calculator to multiply by 3??

But yeah, any number divisible by 9 has its digits add up to a number divisible by 9.

Since the math was too complicated for me, I did an old school calculus trick, which is... are you ready for this?

The answer is always 1!

And it turned out to really be the right answer. In my case at least :P

You have to be careful about order of operations (if you used a calulator and it automatically thinks about order of operations, you had an error with step three where you first add 3, THEN multiply the new result by 3): Here's my analysis:

You pick x.
Your result after step three/four is: 3(3x+3), or 9x+9.
Note this is algebraically equivalent to: 10x+9-x.

To get your final result, after step five, you add the ten's place to the one's place:
The ten's place is: x
The one's place is 9-x.
The result is x+9-x = 9 = BobG... he's MY role model.

The rest of you must be somehow including the square of the page number.:biggrin:

Only Gokul seems to be able to think outside the box. Sometimes so far outside the box that he seems almost invisible. :rofl:

For the record, my favorite number between 1 and 9 is [tex]\frac{17}{9}[/tex]

Oh, wait. Jimmy Snyder's favorite number might be 16/9 and who knows what Cyrus's favorite number is.

No, my favorite number between 1-9 is 17. I ran all the operations you recommended and after much work, three broken crayons and dozens of crumbled up sheets of paper I came up with the answer 7. And amazingly, Paris Hilton is my role model. How does it work?

17 is a bad one, jimmy.

1) Pick your favorite number between 1-9 (17)
2) Multiply by 3 then (51)
3) Add 3, then again Multiply by 3 (I'll wait while you get the
calculator....) (54x3=162)
4) You'll get a 2 digit number....(maybe a 3 digit number)
5) Add the digits together (9)

and who's your daddy? BobG!!!

Wow! Your role model must be a real dufus. I tried it again and got 7 again. Did you remember to carry the hypoteneuse and cancel the subscripts?
