$$($$$$\overline a \overline b \overline c)$$$$+$$$$($$$$a \overline b \overline c)$$$$+$$$$($$$$\overline a \overline b d)$$
is this reducable?
I'm new to this as you may be able to tell, but I've went through this and have not found a way to reduce it, well I thought I had but then when I make a truth table the results don't match. Please help me out if you can, I'd greatly appreciate it.

edit: is $$\overline b \overline c$$$$+$$$$\overline a \overline b d$$ the answer?

The answer looks right to me. Btw, K-maps are helpful for these problems.

yeah, thanks. We just learned about kmaps today in class as a matter of fact. seems much easier than trying to reduce through algebra lol
