62 = 49?
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.
How can you change the statement below into a correct equation? You may freely move the digits but do not remove or add any new digits or symbols.
62 = 49
Move the 6 to the top right of the 2, so it represents 2 to the power of 6. Rotate the 9 by 180 degrees and place it in front of the 4.
2^6 = 64

|I think that this teaser should go in the MATH category instead. |

|I love this one |

|Another answer... 6^2 = 4x9 = 36|

|That does not work as you can't add the 'x' sign.|

|Very creative; good job!|

|Great teaser! As for the category, I think the 'Trick' category is appropriate since you have to rotate the 9 into a 6. That is definitely not a mathematical property/operation. Besides, it was the category that clued me into how to solve it. |

|I thought it was kinda dumb It wasn't really a teser it was like a math kind of challenge. I don't really think it belongs in this section.|

|Very clever |

|Just one question though.... Where'd the '^' come from?|
May 18, 2010
|the ^ just represents that you have to put the 6 above the 2, because you can't do that when you're typing. |

|soooo....... this is trick how?|

|In one sense, it's not a trick, because you do just move the digits around as stated. However, because the '2' moves in an unusual way, it was thought to be better in the 'Trick' category. I think it would fit equally well as 'Math'. Either way, I hope it's still fun enough and a bit of a challenge. |

|You got me... |

|This puzzle is not fair. The instructions clearly say that you can not add anything and yet the solution contains a '^' symbol. Someone needs to check the submissions a bit more carefully before posting them.|

|Hi Wendifly - and welcome to Braingle!|
I'm sorry you didn't enjoy my teaser. However, please read the solution again more carefully - it states that you move the 6 to the top right of the 2 - that makes "2 to the power of 6", which equals 64. The 64 is obtained by rotating the 9, as explained. The "^" is not needed in the answer. I simply used that at the end to re-state the equation.
In the Trick category you have to be quite lateral in your thinking - also rotational in this case!
I'm sure you'll find plenty here to challenge and satisfy you.
I've written this not so much in self-defence, as to defend the Editors who have very high standards - as you will find when you start submitting your own creations!

|YOU SAID NO SYMBOLS CAN BE ADDED! This teaser is wrong! |

|What symbol has been added, Coolnine? Please check your criticisms carefully - some of us spend a lot of time writing, checking, evaluating and editing teasers for you. Of course, they are not perfect, and mistakes do occur. Not this time.|
Please read the solution again carefully, and my comment above to Wendifly.

|Lol, I got it. Anyways, I think it shud be in the math category too.|

|dalfa, you don't just move a number to the corner of another number to make it a power. You have to resize it too. I was close though. I thought about rotating the 6 or 9 but still could not get it to come out.|

|Tilt the right ends of the equals sign in to make the greater than sign. = > |

|Hi Zembobo. There is no law of mathematics that states that an index or exponent MUST be written in a smaller type. That is, of course, a pragmatic convention, but NOT part of the definition. |
