I'm pretty unfamiliar with the subject, so my reply may not be very helpful, but I'm wondering: is addition the same as XOR and multiplication the same as AND? This would lead to

0 + 0 = 0

0 + 1 = 1

1 + 0 = 1

1 + 1 = 0

0 * 0 = 0

0 * 1 = 0

1 * 0 = 0

1 * 1 = 1

If so, then a (probably slow) way of solving is to construct an 8-row truth table and then find a simpler expression from that. I'm curious to see what people more experienced with these problems post. - Jun 9th 2010, 09:31 AMAckbeet
Just to use slightly more standard syntax: you want to simplify

, correct?

Are you wanting to put the result in disjunctive or conjunctive normal form, or are you just trying to minimize the number of logic gates required?

Note to undefined: in digital logic, at least, the plus symbol is usually the inclusive or, and you use something like for exclusive or.

I would probably use Karnaugh maps or DeMorgan's rules to simplify. - Jun 9th 2010, 09:33 AMAckbeet
Incidentally, this question really ought to be in the Discrete Mathematics, Set Theory and Logic forum, not in Calculus.

Ya, that the method of using Boolean algebra, but i got compare to the Boolean algebra with Karnaugh maps, the result are not the same. :(

Show us what you did. I'm a fan of disjunctive normal form myself. What did you get for that?

Ya, at first De morgan's rules is needed.

There are two steps to simplify are using the rules of Boolean Algebra and karnaugh map.

its mean that i only need to simplify the question.

Here my step:

i got change the question.

After DeMorgan rules:

Maybe im stuck at here. - Jun 9th 2010, 09:56 AMundefined

For disjunctive normal form, I got

.

Is that what you got? If so, what did you do then? - Jun 9th 2010, 11:59 AMp0oint

Now here is the thing you need to do so you can create the karnogh map:

Remove the duplicates:

Karnough map:

1 1 1 1

0 0 0 1

Take the 4 neighbour '1' (1st row of karnough map) and 2 neighbour '1' in the right angle.

The minimization is: yz'+x'
