Experiment 9 - Computation Rules of the Boolean Algebra

So far you discovered the properties of the logical operators. Before you combine logic operators, you need to know two computation rules of the Boolean algebra, the priority and bracket rule...

Priority Rule

The order of the logic operations is...

• The NOT operator is executed before all other operators.
• The AND operator is executed before the OR operator.

The formulas and logic diagram illustrate this...

Logic diagram priority rule AND operator.

Bracket Rule

In order to change the priority of the operator you use brackets. The operators enclosed by two brackets have priority...
