# Help with Boolean algebra

Posted on 2013-12-08

I did the truth table for this function, and I get that the output is the not of c.   However, I cannot do the boolean  algebra on this (Or  DeMorgans)  that reduces it to the not of c.

( a*b + not(a*c) )  *  not(c)

Thanks.

Then you should have something in the form
(X+Y)*Y which is the same as Y
