What is the result of A + 1?
Remember, what happens when you add one to something?
What is the result of A ∙ 0?
What do you get when you multiply by zero?
What does the Null Law A + 1 equal?
Consider if there's any scenario where adding 1 would give a different result.
True or False: A ∙ 0 = A.
Think about the effect of multiplying by zero.
You have three inputs A, B, and C where the expression is A + B + C + 1. Simplify this expression using the Null Laws.
What happens when you add one in Boolean expressions?
Given the expression (A + 1)(B + 0), simplify it.
Look to apply the Null Laws to reduce terms.
