    12. This is a version of dozens going around FB (though without including any brackets)

    12. Are you sure you just created it? A quick google shows the identical question appearing on any number of sites going back years. I see from your Profile that you a teacher in the USA. Is the arithmetical order of operations, BODMAS to me, taught in the US?

    I wonder if @Shin0bi3Z thinks the answer to
    is 3 or -13?

    No trick this is a straight forward question that use PEMDAS.

    No I did not create this one. I solved it and thinking of preparing this question for some of my students. I wanted to see what do you think about it. Is it too easy for them or not?
    Yes BODMAS is taught but it is called PEMDAS, where
    E-exponent and everything else is the same.

    The answer would be 3

    There are problems that do repeat you are right about that. What I seek is how do we creatively take something that is old to students and take a new spin on it?

    You are right I will have to rewrite my question better, thanks for the feedback.

    Depends how old they are! I'm not a maths teacher though, so I'm not really qualified to answer that.

    Is the first operation a plus or a divide ? My elderly eyes are failing me.
  13. Shin0bi3Z

    Shin0bi3Z New commenter

    It is a plus.

    Your thoughts are valid and important.

    Yes B is the answer.

    More interesting would be to insert plus, minus, multiply, divide and brackets to obtain different answers.

    3 3 3 3 3 = 4
    3 3 3 3 3 = 0.25
    3 3 3 3 3 = 0
    3 3 3 3 3 = 81
    3 3 3 3 3 = 1

    Better still might be a competition to see who could find the greatest number of possible answers.
