Why the Mix-Up?
The confusion comes from how hidden multiplication (like 2(4)) is seen compared to normal division. Before, hidden multiplication was done first. Now, multiplication and division are treated the same, going left to right. This change in how we see it is what the debate is about, with each side saying their way is right.
Math experts know it’s unclear. Mike Breen from the American Mathematical Society said that while 16 follows the strict PEMDAS, the unclear writing makes 1 a possible answer. He said to write the equation more clearly, like:
(8 ÷ 2)(2 + 2) for a clear 16, or
8 ÷ [2(2 + 2)] for a clear 1.
Expert Views: Clear Math Talk
Rhett Allain, a Physics Professor at Southeastern Louisiana University, talked about the debate, saying it shows how important clear math talk is. Pros use clear formulas, but in normal talk, unclear writing can lead to different answers.
Allain said this debate isn’t just about solving a math problem—it’s about how we share math ideas. In things like engineering or programming, unclear equations can cause big problems, so clear writing is key.
