    Oh good grief it's 1.
    No it's not. 3x0 = 0 so it's 7 - 4 +0 +1 = 3 + 0 +1 = 3 + 1 = 4

    Haha I said the answer is 1 as soon as I saw it. I assumed that the 3x0 part wouldn't be thought of as zero unless it was in parenthesis.
    Like 7 - 4 + (3 x 0) + 1 <--- That to me, reads as 7 - 4 + 0 + 1 which equals 4.
    When I read the equation as it was posted, I see anything before the zero as irrelevant, since anything multiplied by zero equals zero.

    But math was never my strong suit.... My mom was the Math major. hahaha

    Parenthesis first...which you are correct. Then multiplication or division (from left to right). Then subtraction and/or addition.

    But there just wasn't the parenthesis in this one.

    In "Order of Operations" Multiplication/Division comes before Addition/Subtraction, so it kind of is like it's in parenthesis, since you do it first.
  • Would have been proper to include the ( and ) and I think some would not have gotten it wrong. They were sort of set up to fail but should have known about the order of operation.

    I have a question, can somebody write the numerical representation of eleven, hundred, thousand?:bigsmile:

    The "and" what? lol. How were they set up to fail? I guess a lot of teachers set students up to fail.


    Wait.
    I think they do

    bowhunter meant the open and close parentheses.

    There's a reason I had to take remedial math in college... hahaha

    But I was also taking advanced English courses at the same time. We all have our strengths and weaknesses... :wink:

    People, People...

    Please Excuse My Dear Aunt Sally

    Parentheses
    Exponents
    Multiplication/Division (in the order they appear)
    Addition/Subtraction (in the order they appear)

    Ohhh *face palm* Because it doesn't need to be there, silly.

    And yes, that's very true. I SUCK at creative writing. It's the death of me. Math isn't exactly my strongest subject either. Don't mess with me in social studies and science though ;)

    ^^^I was always horrible at algebra so this makes no sense to me at all. My co-worker used a calculator & got 4. I used old fashioned math & did the problem from left to right & I got 1. I guess it depends which way you were taught.

    Math is all the same. That's the "magic" of math. It's the same in every language, no matter who teaches it. The rules are all the same. Calculators are programmed to use order of operations, therefore the calculator is right.

    the ´magic´ of math???.. my *kitten*!, F math!
