You open your mouth to exclaim your surprise. OR gates are equivalent to Boolean addition, and AND gates are equivalent to Boolean multiplication. . Applied to digital logic circuits and systems, the true-false statements regulate the relationship between the logic levels (logic 0 and 1) in digital logic circuits and systems. You’ll pick them up in stride as we move across this course. If it is an AND operation, we will place an AND gate similarly. Or we can define that as “The compliment of the sum of two variables is equal to the product of the compliment of each variable”. Laws of Boolean Algebra and Boolean Algebra Rules.
