A very urgent question :
Please simplify this logic expression for me with helping boolean algebra :
A'C'D + A'BD + BCD + ABC + ACD'
I know that must use consensus theorem .
my solve :
STEP 1 : Terms 1 & 3 ---eliminate---> Term 2
STEP 2 : Terms 3 & 5 ---eliminate---> Term 4
STEP 3 : Terms 2 & 4 ---eliminate---> Term 3
But truth table said step 3 is incorrect . but why ?
please tell me why step 3 is Wrong ?
and tell me What is the simplest form of it ?
