Is anyone any good at it?? I've got 3 different equations which i've simplified as much as i can and i cant get them any further but i'm sure they will simplify more.

Cant be arsed to post them up if no-one knows it, so if someone does, then i'll type them up

ok, this is what i've got, more or less straight from the karnaugh (sp) mapping

i know that i can group some, but i think there are some simplifications that can be done other than grouping:

ok, there is no way i can do a "NOT" function in the normal way, so i've used an underline, instead of a line on the top.....

Qa is one term, Qb is one term, Qc is one term

DC = A.R.Qa.Qb.Qc + A.R.Qa.Qb.Qc + A.R.Qa + A.Qa + Qa.Qc

thats the first one

oops, i've simplified that to:

Dc = Qa.Qb.Qc + A.R.Qa + A.Qa + Qa.Qc

the second one is:

Db = A.B.R.Qa.Qb.Qc + A.B.R.Qb.Qc + B.R.Qa.Qb.Qc + R.Qb

In the third one, i've used (+) as EXOR (exclusive OR)

Da = A.B.R.Qa.Qb + B.R.Qc + A.B.R.Qa + B.R.(Qa(+)Qc) + A.B.R.Qb

I could have helped a year ago, but thankfully I've wiped all of DeMorgan's laws out of my mind

Commutative laws can seriously SMB.

Google for "Boolean algebra rules" or Boolean algebra laws
