# Math Help - Logic

1. ## Logic

(¬a.¬b.c.¬d)+(¬a.¬b.c.d) +(¬a.b.¬c.d)+(¬a.b.c.d)+(a.¬b.c.d)+(a.b.¬c.d)

+ = OR
. = AND
¬ = NOT

How do I simplify as much as possible?

2. The most simplified equation that you can get is either

a'b'c + a'bd + bc'd + b'cd

or

a'b'c + b'cd + bc'd + a'cd

. You try 1st if still not sure i will show you how to get it. The equation that i got above is by using K-Map. I hope it helps.
