8/2(2+2) = 8/2(4) = 4(4) = 16

division and multiplication have no priority over each other regardless of whatever stupid pneumonic you learned thus you simply do in order from left to right
4(4) = 16

The symbol implies a fraction. Why do you think it has a line between two dots?

Division implies a fraction, therefore everything after the symbol is intended to be in the denominator, its 1 unless they do (8/2)(2+2), then it is 16

IRL you should never write problems like this.
Getting it right or wrong wrong does not make you smart or stupid it just shows how unclear this fucking format is because everyone understands the math required to solve it, but fails because of the ambiguity of the presentation.

It's not an order of operations problem but a case of unfortunate notation.

Division isn't associative so expressions like the one in the picture are ambiguous. For it to make mathematical sense, it should be written either as 8÷(2(2+2)) or (8÷2)(2+2). That PEMDAS thing shouldn't be thaught like it was a mathematical law.
