# Thread: Don't know where to start on this Boolean algebra question

1. ## Don't know where to start on this Boolean algebra question

This looks similar to some of the other questions I've been doing butI dont know where to start.I have to write the complement of this Boolean function and simplify it with DeMorgan's law and other Boolean theorems.

X=ABC+ ¬B¬C¬D

2. ## Re: Don't know where to start on this Boolean algebra question

I suspect it looks like:
$a b c+\neg b (\neg c (\neg d))$

3. ## Re: Don't know where to start on this Boolean algebra question

Do you know what those symbols mean? Do you know what DeMorgan's Laws are?
