I have no problem with 2(a+b).
I have a problem with 8/2(a+b).
I know PEMDAS gives some sense of order here but not everyone knows PEMDAS so I don't know the intent of the original writer.
I think I will side with Excel, which, when presented with the original equation asks for clarification: "Do you accept this interpretation?". That would be my answer.
Maybe we should replace PEMDAS with EXCEL. More people seem to be familiar with EXCEL than PEMDAS.

I'm using 'Numbers' on my macbook and 'LibreCalc' on my desktop and they both agree with PEDMAS.

The past nine pages are a good example of why so many people have trouble with math. : )

Hmmm.
Maybe they used PEMDAS rules when they created the calculator programs.

it's the order of operations: parentheses, exponents, multiplication, division, addition, subtraction. Do the operations in that order to get the correct answer. Do them in a different order to get the answer you want.
