Hey there guys, how is everyone ?
I have another basic boolean question for the gurus out there. I am slowly working my way through my work book and came across this question.
prove that A+AB=A using boolean algebra.
Now i know that A+AB=A as it a basic rule used to simplify boolean expressions, however actually going through the process is a little difficult for me. When i looked at the answer it showed this:
Step 1. A + AB = A
Step 2. A(1 + B) = A
Step 3. A=A
What I was needing help with is I dont know what they have done with step 1 to get to step 2. I see they have factored out the A out of both terms but i dont understand how they have expanded the B term and then canceled it out. If someone could briefly explain to me the steps to go through it would be great !!!
Cheers
