    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.

    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
