 # What are De Morgan’s Law explain?

What are De Morgan’s Law explain? De Morgan’s First Law states that the complement of the union of two sets is the intersection of their complements. Whereas De Morgan’s second law states that the complement of the intersection of two sets is the union of their complements. These two laws are called De Morgan’s Law.

What are the two De Morgan’s Law? DeMorgan’s first theorem states that two (or more) variables NOR´ed together is the same as the two variables inverted (Complement) and AND´ed, while the second theorem states that two (or more) variables NAND´ed together is the same as the two terms inverted (Complement) and OR´ed.

What is De Morgan’s Law in truth table? De Morgan’s Law says that ‘(P and Q)’ is logically equivalent to ‘not (not P or not Q)’. If it’s logically equivalent, then it should be that ‘(P and Q)’ entails ‘not (not P or not Q)’ and that ‘not (not P or not Q) entails ‘(P and Q)’. Let’s look at this using a truth table.

What is De Morgan’s Law formula? De Morgan’s Law of Union: The complement of the union of the two sets A and B will be equal to the intersection of A’ (complement of A) and B’ (complement of B). This is also known as De Morgan’s Law of Union. It can be represented as (A ∪ B)’ = A’ ∩ B’.

## What are De Morgan’s Law explain? – Additional Questions

### How is DeMorgan’s law used?

DeMorgan’s Laws
1. Combine sets using Boolean logic, using proper notations.
2. Use statements and conditionals to write and interpret expressions.
3. Use a truth table to interpret complex statements or conditionals.
4. Write truth tables given a logical implication, and it’s related statements – converse, inverse, and contrapositive.

### What is De Morgan’s first law?

In algebra, De Morgan’s First Law or First Condition states that the complement of the product of two variables is corresponding to the sum of the complement of each variable. In other words, according to De-Morgan’s first Laws or first theorem if ‘A’ and ‘B’ are the two variables or Boolean numbers.

### What is De Morgan’s Law example?

For example, the statements “I don’t like chocolate or vanilla” and “I do not like chocolate and I do not like vanilla” clearly express the same thought.

### What is De Morgan’s theorem with example?

DeMorgan’s Theorem states that inverting the output of any gate results in same function as opposite type of gate (AND vs. OR) with two inverted variables A and B. It is used to solve Boolean Algebra expressions. It perfomes gate operation like NAND gate and NOR gate.

### How do you remember De Morgan’s Law?

An easy way to remember De Morgan’s Laws is through the rhyme: “break the line, change the sign”! Since the values in the 4th and last columns are the same for all rows (which cover all possible truth value assignments to the variables), we can conclude that the two expressions are logically equivalent.
