Amazing deception! Please forgive me if I use this as a teaching tool in the future :) it's just too cool.

Ha ha.... Great question! :0)

Nice try, Mr. Staff! The proof is much more boring than the solution, sadly. By the way, is this really level 2? It's difficult!
Clever, perhaps TOO clever - Stewie - Seriously, good one!
Didn't think of that!! (+1)
Didn't think of that
'The operators can not be moved' implies that new ones can not be added. But exponentation has been added here.

"The operators cannot be moved" only refers to the operators already present, so I don't see how that invalidates the introduction of exponentiation implicit in the repositioning of the first 6 . In any event, the question was simply designed to prompt people to "think outside the box" to find an answer. Logic questions can be tricky to word so that no misunderstandings arise, so I'm sorry if that has been the case for you. However, enough people have come up with the intended answer that I feel justified in leaving the wording as is.

@Vishwash Kumar Γξω – @Brian Charlesworth If adding operators are allowed then this can also be a solution . Right 6/2 - 6/3 = 1 Without shifting anything .........................................................................................................................................................

@Vishwash Kumar Γξω – Well, in this case you've moved two of the digits, as well as adding two division signs. With the exponentiation solution, only one digit is moved and no actual "marks" are added, since positioning the 6 to the upper right of the 2 implies exponentiation without adding any extra signs.
When I first posted this problem I expected some disputes but they never came, and now that the problem has stood the test of time, (1253 views so far and 224 solvers), I don't think that there is any point in changing the wording. It was just meant as a fun problem with an interesting twist. :)

@Vishwash Kumar Γξω – Well at least your solution isn't one of the choices... And you must shift something.
Amazing Problem !!
Didn't think of that .
