Not sure if DevRant material, but I am hecking bamboozled. What else have I calculated wrong.

Having debates on order of operations. The one that is hot again is the 6÷2(2+1).
Programming and actual order of operations says the answer is 9, but everyone argues it is 1. Well before 1970 that was the case. SMH. Despite showing them the rules and work, they still say theirs is the correct way.
With programming and Excel formulas I deal with every day I do this without even pausing.

Really sad in 2016 when I have to teach an assistant manager and her underling in a different department about PEMDAS.

We deal with excel on a daily basis and the math always follows that. Had to explain in very simple steps how it works. Then was asked what an exponent was. *weapons grade face palm*
