The value of the expression (5-7)(-8+4)/2-(-6) is


The answer key says -33.

????????????

  • Math -

    (5-7)(-8+4)/2-(-6)
    (-2)(-4)/2-(-6)
    8/2 - (-6)
    4 + 6
    10

    or if the whole 2-(-6) is in the denominator,
    (5-7)(-8+4)/(2-(-6))
    (-2)(-4)/(2+6)
    -8/8
    -1

    I'm not sure how they got -33. Probably there's typo error or something...
