Hmm, do AND and OR have the same precedence, or doesn't it matter at all?

As in, can you repost your original equation, but with brackets added?
I see too many possiblities to interpret it. For example:

• ((a0 AND a0) OR (d1 OR d1)) AND d0 ==> (a0 OR d1) AND d0
• (a0 AND a0) OR ((d1 OR d1) AND d0) ==> a0 OR (d1 AND D0)
• a0 AND (a0 OR d1 or d1) AND d0 ==> a0 AND d0
• a0 AND (a0 OR (d1 OR (d1 AND d0))) ==> a0
• ...
