Hello,
I am having so much trouble understanding how to simplify boolean expressions. I know how to use the k map but it is not helping me with this problem. i need to simplify an equation that i think is already reduced down it is
AB+A'B'C
i even tried the truth tables to see the output of the circuit and match the answers of the truth table to the other 5 possible answers that were given and i have no luck. I am lost. thanks in advance
AB+AnBnC

Cn C
AnBn 0 1
AnB 0 0
AB 1 1
ABn 0 0

Then I get
ABCn+ABC=AB+AnBnC
I get the same answer I started out with

For what it's worth, I didn't come up with anything either.

What were the other five answers?

Is this a duplicate thread of the above query? If so, let me know so we can keep all this in one place.

Thanks.

Dave
