Casio anomaly or gremlin or bug...

[Matt Agajanian]

I'm sorry. I meant no disrespect. At this point, I am trying to ascertain some clarity. Both sides can defend which is right. But isn't mathematics predicated on accuracy and disambiguous results?

In a science as disipline and structured as mathematics, I find that it becomes confusing when this kind of ambiguity surfaces. I thought that PEDMAS/BODMAS rules were identical, infallible, and rigid. Now, with US versus European interpretation differences, it's frustrating.

Please clarify because this variation of interpreting PEDMAS/BODMAS seems to say that mathematics rules are flexible instead of having a standard rule base.
