I consistently keep getting this question wrong, and I cant figure out why
(a+b)(b+c)=ac+b
I put this as the answer:
ab+bc=a+cb
I do not understand why that is wrong

Aren't you supposed to be solving it? i.e. finding the possible values? – Denziloe Mar 07 '17 at 21:01

This is Boolean algebra which is completely different than regular algebra. I am supposed to be finding the dual of the first equation – Camden Kitchen Mar 07 '17 at 21:03

I said this was Boolean algebra because it has to do with computer science – Camden Kitchen Mar 07 '17 at 21:04

I'm voting to close this question as off-topic because it is about boolean algebra and [math.se] instead of programming or software development. – Pang Mar 10 '17 at 01:18

(a || b) && (b || c) = (a && c) || b
It's written in c style (may be better for understanding). It means that if we have b = true the result is true, if b = false the result is depends of a and c in couple. Also we can find result for each tuple of (a, b, c) and for identical tuple we have identical results.
