Thread: Stuck with logic gates

I know each of the logic gates what what the outcome would be if but I have a practice question here that I just don't really know how to draw.

X = ((NOT A) AND(NOT B)) OR A

How would I draw this using logic gates or a truth table? If you could draw it in paint or something and then upload it that would be amazing.

Thanks.

This webpage answers both questions.

Wow what an awesome site. Thanks but does it take into consideration the brackets?

Nevermind I see that it does. Thanks this site is actually amazing.

Since I have already drawn the circuit...

Thanks emakarov. That makes sense..... the 2 NOT gates and the AND gate are read like NOT a AND NOT B and then the OR gates comes in for OR a?

NOT a AND NOT b OR a
