Boolean logic simplification

  1. Mar 28, 2013 #1
    Hello, I can understand most boolean simplifications however I cannot grasp this one:

    where the ' symbol represents a NOT.

    Without using Karnaugh maps can someone please tell me how to go about simplifying this expression ?

    Thank you kindly for any help.

    I see mismatched parentheses.

    A good start would be to expand and simplify this expression: (A+C+D)(A+C+'D)

    Show your working and see how far you can get.
