According to the Null Law (Annulment Law) in Boolean algebra, what is the result of A OR 1 (written as A + 1)?

The Null Law for OR says that OR-ing any variable with 1 always gives 1, regardless of A. This makes sense because OR only needs ONE input to be 1 to produce a 1 -- and here, one input is already fixed at 1, so the condition is already satisfied no matter what A is. The result is forced to 1 every time, which is why this is called an 'annulment' -- A's actual value gets completely wiped out of the result.
