when working with numbers (negative and positive)inside absolute value bars are they considered positive and bars removed?

  • MAth -

    Do all calculations inside the bars following the usual rules of arithmetic.
    If your answer is positive, make that your answer.
    If your answer is negative, ignore the negative sign, and state the positive result.

    That is | anything in here | will always produce a positive (or zero) result.

  • MAth -

    as it applies to your previous problem

    |30|/|10| + |-2+7|/5 x 8
    = 30/10 3 + |5|/5x8
    = 3 + 5/5*8
    = 3 + 1*8
    = 3+8
    = 11

  • small typo - MAth -

    the second line of the solution should say :
    = 30/10 + |5|/5x8

    has no effect on the rest

  • MAth -

    ok
    new problem |-32|/8 - |9x2| + |4| =
    32/8 - 18 + 4 = -10



    am I on the right track

    Yessss!!!
    Looks like you got it
