- Boolean algebra - Wikipedia
In mathematics and mathematical logic, Boolean algebra is a branch of algebra It differs from elementary algebra in two ways First, the values of the variables are the truth values true and false, usually denoted by 1 and 0, whereas in elementary algebra the values of the variables are numbers
- What is a Boolean? - Computer Hope
In computer science, a boolean or bool is a data type with two possible values: true or false It is named after the English mathematician and logician George Boole, whose algebraic and logical systems are used in all modern digital computers Boolean is pronounced BOOL-ee-an
- BOOLEAN Definition Meaning - Merriam-Webster
The meaning of BOOLEAN is of, relating to, or being a logical combinatorial system (such as Boolean algebra) that represents symbolically relationships (such as those implied by the logical operators AND, OR, and NOT) between entities (such as sets, propositions, or on-off computer circuit elements)
- Boolean Algebra - GeeksforGeeks
Boolean Algebra is a branch of algebra that deals with boolean values—true and false It is fundamental to digital logic design and computer science, providing a mathematical framework for describing logical operations and expressions
- What Boolean Logic Is How It’s Used In Programming - Codecademy
Boolean logic is a type of algebra in which results are calculated as either TRUE or FALSE (known as truth values or truth variables) Instead of using arithmetic operators like addition, subtraction, and multiplication, Boolean logic utilizes three basic logical operators: AND, OR, and NOT
- How Boolean Logic Works - HowStuffWorks
A subsection of mathematical logic, Boolean logic deals with operations involving the two Boolean values: true and false Although Boolean logic dates back to the mid-19th century, it became foundational to modern computer programming and data querying through a method called Boolean algebra
- What is Boolean in computing? – TechTarget Definition
In computing, the term Boolean means a result that can only have one of two possible values: true or false Boolean logic takes two statements or expressions and applies a logical operator to generate a Boolean value that can be either true or false To return the result, operators like AND, OR, NOT, etc are used
- Boolean Algebra - Math is Fun
Boolean Algebra is about true and false and logic The simplest thing we can do is to "not" or "invert": We can write this down in a "truth table" (we use T for true and F for false): We can "and" two values together Both must be true for the result to be true: Example: If we cut the grass and wash the car we get ice cream!
