That's an example of why I like the liberal use of parenthesis and operators. They leave no doubt.
For 16 I would have written it as (8/2)*(2+2) or even (8/2)(2+2) is better.

Here's one of the comments from the article:
8÷2X(2+2) = 16 8÷2(2+2) = 1 Final answer. People who are poor in math will add that multiplication sign in their delusional minds and then follow PODMAS to come up with 16 People who are proficient in math will not add that multiplication sign and still follow PODMAS exactly and come up with 1. People like me who are stuck on RPN come up with 1 too. Interesting. I use a 41CV with "Applications" and Math/Stats ROM pacs. I get 16 The calculation takes the parenthetic first (2+2) and stores the resulting 4: STO 01 (or in ALPHA STO A) It then solves left-to-right: 8 ENTER 2 ÷ RCL 01 X 16

Eight in the numerator over 2 times 4 in the denominator is how I took it. It is ambiguous. I consider it a poorly written problem. If I saw it in code, I would question whether or not the original programmer knew what the result should be.

2(2+2) and 2*(2+2) are synonymous. The * is implied whether it's written or not. The only way the expression can be used as a denominator is to write it as (2(2+2)). Otherwise it's solved 8 / 2 * (2+2)

If I saw it in code, I would question whether or not the original programmer knew what the result should be. Hm? What's wrong with a / b * (c + d) ? Of course in the real world if it was just constants you or the preprocessor would evaluate it. As 16.
