To DeMorganize a Boolean expression, you apply De Morgan's laws, which involve changing the operation and flipping the logic of the expression. Specifically, the AND operation becomes an OR operation, and vice versa, while the NOT operation is distributed across the variables within parentheses. For example, DeMorganizing the expression ¬(A AND B) would result in ¬A OR ¬B. This process is crucial for simplifying and manipulating Boolean expressions in logic and computer science.

Oh, dude, Demorgan's theorem is like when you flip AND to OR and vice versa while negating everything inside the parentheses. So, if you wanna Demorganize a Boolean expression, just swap those operators and throw in some negations. It's like math's version of a makeover, but way less exciting.
Ah, demorganizing a Boolean expression is like a happy little transformation. You simply switch AND to OR, OR to AND, flip the signs, and make sure to put parentheses in the right places. Remember, there are no mistakes, just happy little accidents in the world of Boolean algebra.
The simplest way to describe this action is to demonstrate using a simple truth table. This is not intended to be an in depth study of the theorms but a simple demonstration of how a trivial equation can be demorganized. Given a simple boolean equation !A+!B=1. One could show in a truth table. !A !B !A+!B (fully inhibited OR function)
0 0 1
0 1 1
1 0 1
1 1 0 Demorganizing (hypersimplified method)
1) NOT all variables
2) NOT the equation
3) Invert the function (AND to OR or OR to AND)
Iterative steps yeilds
!A becomes !!A which is the same as A
(!!A + !B) = (A+!B)
!B becomes !!B which is the same as B
(A +!!B) = A+B OR function becomes AND
(A+B) = (AB)
NOT the full equation !(AB) = !A+!B Truth table for the new equation (which happens to be a NAND function) A B AB !AB !A+!B
0 0 0 1 1
0 1 0 1 1
1 0 0 1 1
1 1 1 0 0
The idea is to get a simpler expression. If you need to build the hardware to implement a specific boolean expression, you can actually save money if the expression is simpler - and thus, you need less components.

To simplify a circuit you must first find a Boolean expression for the circuit and then apply Boolean algebra to take it down to the simplest form, to implement the fewest gates.
