I have attached a K-map to this post. In the picture, why shouldn't I use the region circled by me in orange when simplifying the SOP expression? Or should I? I thought I should make use of the "don't care" terms to maximise the regions as much as possible to make the final expression the simplest?
Also, in this case, when asked for the number of prime implicants, do I only count the ones I used in the simplified equation or do I also include the other variety of prime implicants that I did and didn't use in my final expression in my count?
Thanks!
