    24. The logic expression A ⋅ (B +C) is equal to
    A. A +B +C
    B. A +B ⋅C
    C. A +B ⋅C
    D. (B) and (C)
    E. None of the above

    25. The expression F = A + AB + ABC is equivalent to
    A. F = AB+B+ABC
    B. F = A+B+C
    C. F = ABC
    D. (B) and (C)
    E. All the above

    32. The logic equation A + A·B + B·C + C is equal to:
    A. A·B + B·C
    B. A·B + B·C + C
    C. A + A·B + B·C
    D. A + C
    E. None of the above

    24. C
    25. D
    26. D

    Can someone explain why?

    Have my engineering exam tomorrow and the only thing I seem to be having problems with is logic equations.

    Thank you
