1. The problem statement, all variables and given/known data Okay, I have question I was pondering about for a while... If I had the equation below and wanted to transform it into a K-Map, is the only way I can do it to expand it completely? Are there any shortcuts? 2. Relevant equations This is just a random equation out of my mind : (A+B+C)(A+B'+C)(A+B+C')(A'+B+C)(A'+B') So I been taught when handling K-Map if I get a SOP, I would make all of portions similar to include all 3 variables eg.(A+B+C) then convert them to binary, invert them and take their sum to map it into the K-Map as a short cut. Example for (A + B + C) I would take 111, invert it 000, the decimal will be 0, and then I map this as a 0(Maxterm or was it minterm @_@) into the 0 portion of the K-Map. But I was thinking is there anyway to convert the portions of my above equation to a (A+B+C) form easily or do I have to expand them to make it a POS then map it into a K-Map.
