In boolean algebra, `not (A or B)` is equivalent to `not A and not B`
(De Morgan's law). I double negate

One more note: I used round parenthesis in the diagrams above to

Once a function gets beyond about six or seven lines long, it's a bit
hard to read, and harder to get the indentation right. You're having
difficulty with the indentation, but that's often a sign that the
function is too big to read comfortably.
Can you break the function down into a few pieces?
