A'BAC+ABC
=A'B(A+C)+ABC
=A'B+A'BC+ABC
=A'B+AC

The underlined AC is supposed to be 2 lines above the AC. I want to know if this simplification is correct.

 

That looks correct to me.

 

erasm,

If you download the program in the link below, then you can verify a logic reduction expression yourself. Are two lines over a logic term supposed to be a double negation? Why not use the less confusing and easier to write apostrophe for negation? Such as A'B(AC)'+ABC
