The answer is 1. When you advance far enough in math you get to chaos theory, quantum physics and swarm dynamics. Then you discover that everything you learned is wrong. (Start with the cat in the box) We as humans are defined because we use the decimal system, our way of calculating value, time and distance.

Depends of rules. If 2(2+2) actually means 2∙(2+2) then 16, if not then 1.
It simple examle, in math there are much more undefined example like matrices, which one you use row-oriented or column-oriented matrix by subscription they looks indentical it can be ether row oriented or column oriented:
|2 4 3|
|6 7 8|
|9 8 2|
Same about ∙ it can be scalar multiplication or dot product in geometry.
Good math article always define operation subscription before writing formula.

16 is only the correct answer when you treat the equation as:
(8÷2)(2+2)
... which it appears that some calculators are doing.
Work backwards to find out what the correct answer is:
8÷2(2+2)= ?
8= ? x 2(2+2)
You cannot bring over the 8÷2 because it is not bracketed.
and so 16 x 2(2+2) is obviously not 8.
The answer is 1.
(8÷2)(2+2)

16 is the result of the question, written in the story:
8/2*(2+2) = 8/2*4 = 16
1 is the result of another question, not written in the story:
8/(2*(2+2)) = 8/(2*4) = 8/8 = 1
The second two brackets make the difference.
At first i was one of the result-is-1-idiots. While i read the story, i got my mathematical intelligence back.
8/2*(2+2) = 8/2*4 = 16
