Hello Ive read the AAC Karnaugh e-book. How would I draw a map for: xy + y'z + xz I started with a 2x4 grid. X = row, YZ = column, using Grey code. When I look at the first term: xy, where would I put the 1? Do I need to separate the 3 variables: x, y, z? How? Is this technique shown in the e-book?
