Mathematics III: PEMDAS

[Grumpier Than Uncle Joe]

Well, is there is a definite way to have a final answer (the right one)?

Yes. Ask Muon2.

Is Muon2 a mathematician?

He has a PhD in physics so one would assume he's adept at math.

6 ÷ 2 (1 + 2) =

In algebraic logic, the answer is 9.  On any calculator (e.g., TI89) that follows algebraic logic you will get 9.  On some low-end calculators, such as those you buy at the Dollar Tree you might get a 1.  Interestingly, on my Casio fx260solar I actually get a 2 as the answer.  Neither 1 nor 2 are the correct answer in the formalism taught in US schools.  Only 9 is correct.

Punch in the sequence 5+3x2= on your calculator.  If your calculator follows algebraic logic, it should show 11 as the answer.  If it follows arithmetic logic, it will show 16 as the answer.  11 is correct here.

I forgot to mention angus knows a thing or two about math.

Attention posters - no one will out nerd angus in this thread.  Don't try.  Peace be with you.
