We were also taught to factor the numbers, with 8 being the top number and 2(2+2) being the bottom number. When we take 8/2(2+2) it becomes thus:

_____8______
___2(2+2)___

Divide 8 by the multiplier 2 and the result is:

_____4______
____(2+2)___

Then:

_____4______
_____4______

The result being 1.

Using factoring you cannot possibly come up with an answer of 16.

I am neither a teacher nor a mathematician. I am in total agreement with you that weasels can take a basic equation like this and try to confuse someone. Going back to what I posted, for the answer to come out to 16 the equation cannot be written as 8/2(2+2). I would sit down with the person if it was possible, and write it out, as above, to show where the misconception is, and suggest they take an algebra class.

Exactly correct! It is a numerator-denominator issue first!

I think the "weaselly" aspect of the problem as stated is that the slash '/' causes the eye to imagine that it's written in fractional notation. Using the divide symbol '÷' would be less troublesome in this regard.

Now, if the slash were large, and the '8' was written higher, then the fractional nature would have been more evident:

8 /
 / 2(2+2)

But then it wouldn't be confusing, and it wouldn't go viral.

I file this viral "conundrum" under: "Play stupid games, win stupid prizes." I.e. IMO it's just a poorly and confusingly stated, and thus stupid, problem.

Makes about as much sense as:
Q: "What is the difference between a duck?"
A: "Because one feet is both the same."
