# Thread: Coin Tricks

1. ## Coin Tricks

by moving 1 coin only how can you make 2 lines of 3 coins.

coin are labelled as

E
ABCD
F

omg i can't place the letter E and F at the top and bottom of C.... Hope anyone can understand

2. Don't you already have 2 rows of 3 coins?

3. sir i mean 2 lines..

pls help me

4. Sorry, I still don't understand. What is it about a line that my answer doesn't satisfy?

5. Move coin D up or down or anywhere you like.

Then you get two lines of three coins, ABC and ECF.

I hope that helps.

P.S. Badge, very smart of you... but aren't those two lines of yours THE SAME? :P

6. ok tnx for your answer.. my teacher will revealed it tomorrow

7. Mine aren't the same: one is abc and the other is bcd

8. ABC and BCD are both extensions of the line BC. It's just one line... ABCD or DCBA. AB, BC, CD, DC, CB, BA, ABC, BCD, DCB and CBA aren't different lines. They're just part of the line ABCD.

9. Do let us know the answer!

10. ABC and BCD are both extensions of the line BC. It's just one line... ABCD or DCBA. AB, BC, CD, DC, CB, BA, ABC, BCD, DCB and CBA aren't different lines. They're just part of the line ABCD.
I see now.

11. Yes, I did. I was just responding to you.

12. Hello,

If you put D to the left of A, wouldn't it work ?

Line DAB and line ECF

13. Oh. I forgot to add... I don't think you can move D to the left of A. I know you'll still get two lines of three coins, but if that's the case, you already have two lines of three coins... ABC and ECF. Moreover, in that case, ABC is a part of the line DABC, which contains four coins. What I'm trying to say is... It's still the same thing. So either REMOVE D, or place it anywhere you like, but not to the left of A or in between ABC. That'll ensure that you get two lines containing THREE COINS ONLY.

I hope I've not offended anyone. People seem to get offended really quickly over here...

Sorry.

Offended ?

Okay, this is my point : you can put D next to A. Because you will distinctly have 2 lines of 3 coins. Whereas in the original situation, you have 2 lines that intersect themselves and which are not really continuous if you decide to separate the lines.

But it's better waiting for the solution =)

15. I get you, Moo. Let's see if both our answers are acceptable.

No, I wasn't referring to you when I said 'offended'. I was referring to badge. He seemed to have gotten angry... because
