Casio anomaly or gremlin or bug...

Lesson: Math is not a Single Eternal Truth. It's a tool, and like any tool, it comes in many designs, all of which are useful for various tasks. Pick a tool, learn how to use it, and then use it, but PLEASE don't waste time trying to convince the world that YOUR tool is the best one, or the only one that should exist, or some kind of Eternal Truth. That kind of debate belongs in a religion forum, not here.

Quiz: Which algebraic order of operations is Eternally True? or is the best one? or is the only one that should exist?

Answer: Those are stupid questions. Re-read the Lesson above.

EDIT: Whoa Nellie, sorry for being so easily annoyed. I didn't have my coffee this morning. Yeah, I'll blame that. <blush>
