a bar indicates a negation; negate first, multiply second, and add last

Answer 2

Okay, I tried to work this out a few times the other day and made a few mistakes so didn't post it, but here goes again. \[\overline{AB+\overline C}+A\overline C +B\]\[(\overline A+\overline B)C+A\overline C +B\]\[\overline AC + \overline BC+A\overline C+B\]\[\overline AC + \overline BC+A\overline C + B(C+\overline C)\]\[\overline AC + \overline BC+A\overline C + BC +B\overline C \]\[\overline AC +A\overline C + C + B \overline C\]\[C + \overline C(A+B)\] thats about as far as I could get it.
