I've been having problems simplifying Boolean expressions with Boolean algebra and Karnaugh maps, I tried to simplify the same Boolean Expression using both ways but the two answers I got were different. Can that happen? After any Boolean expression simplification whether we use Karnaugh maps or Boolean algebra, the answers should be same, right? Or can the answers be different?
I tried simplifying the expression $A'B'C'+A'B'C+A'BC'+ABC'+ABC$. With boolean algebra I got $A'B'C+AB$, and with Karnaugh maps I got $A' + B$.
