Simplify this boolean expression

Homework Statement

~AB+AB~c+ABC

Homework Equations

AB+A~B=A

3. The attempt at solution
~AB+A

A+B

 

[lewando]

Nope. That's not it. The idea behind the Relevant Equation is that if you can "factor out" (B+~B) then it "disappears"-- B+~B = 1, A(1) = A. See if you can find similar factorizations in the Problem Statement.

focus on the AB~C + ABC terms first

I see you are new to PF--welcome. Rules require you to show some effort in order for help to be offered. Otherwise anarchy would erupt and you wouldn't learn anything. Do you need more boolean algebra reference material? You must help us understand what it is that you don't understand.

sorry we can't do that. boolean algebra is very similar to regular algebra:

so for example given abc + abd = ab * (c + d) where a, b, c and d are real numbers.
