Which of the following statements is NOT true?
Boolean Algebra provides the ability to algebraically simplify logic expressions.
Boolean Algebra is the only way to simplify complex logic expressions.

Which of the following us true (check all that apply)?
When converting a circuit from AOI to NAND or NOR, double inversions (i.e., back to back inverters) can be eliminated.
Any combinational logic expression can be implemented using only NAND gates or only NOR gates.
NAND and NOR gates are called universal gates because there is no difference between their truth tables.
NAND or NOR implementations of a circuit will often reduce the number of integrated circuits (IC) required to implement a logic circuit.
