Ok, so here's the story on this. My teacher was going over Boolean expressions in class, and she couldn't figure out how to simplify this expression. She came up with two different ways and then asked us for help. lol I found this kind of funny. Anyway we have to simplify the expression, and pick which law we used on each step from a list that I posted HERE.

Here was the first statement. I belief to be true.

Given =$\displaystyle \overline{A}B\overline{C}D+\overline{AC}$

#19 =$\displaystyle \overline{A}B\overline{C}D+\overline{A}+\overline{ C}$

#14 =$\displaystyle \overline{A}(B\overline{C}D+1)+\overline{C}$

#2 =$\displaystyle \overline{A}(1)+\overline{C}$

#4 =$\displaystyle \overline{A}+\overline{C}$

I feel this one is correct, because I proved it in the truth table. Is this correct, and is there any missing steps with this statement?

Thanks for the help, Jarod.
