So, I have to do some Boolean algebra and I memorized all of the axioms.
Nevertheless, I still got HUGE troubles in applying them to simplify Boolean expressions/terms.

Like,
(w + x + y + z) · (w + x + y + z) · (w + x + y + z) · (w + x + y + z) = (x + y + z) · (x + y + z) = x + z

I looked through some examples online and in our book. Do you got some advice here?

But that's wrong. Did you miss out negations?

>> No.6555450

(w + x + y + z) · (w + x + y + z) · (w + x + y + z) · (w + x + y + z)
= w + x + y + z
and if you are working with 4 variables
= 1

It's like you guys have never heard of negative numbers, or 0 before.

bit like how you've never heard of a Boolean algebra I suppose

I know nothing about Boolean Algebra but why in the world did you write out (w+x+y+z) 4 times? Are you telling me there's no shorthand for that like a superscript, subscript, or something?

Looks like a product-of-sums notation for a circuit.
