125-10/27/9-(-9)
115/3-9
115/27
want to know if these two problem right

  • algebra - ,

    aside from the ambiguity caused by a paucity of parentheses,

    #1 looks ok
    #2 (-3)^2 = 9, not -9
    but that's ok, since you dropped it in the next step anyway.Other than that, it's virtually incomprehnsible.

    Add some parens so it's clear what is wanted. I can guarantee that 115/3-9 is not 115/27, no matter how you parse it.
