2010-11-05 Boolean+logic 1. Boolean Logic 2. George Boole In1854, George Boole published “An investigation into the Laws of Thought, on which are founded the Mathematical Theories of Logic and Probabilities.” Boole outlined a system of logic and a corresponding algebraic language dealing with true and false values. 3. It’s called Boolean Logic.
Boolean Logic is a form of algebra which is centered around three simple words known as Boolean Operators: “Or,” “And,” and “Not”. At the heart of Boolean Logic is the idea that all values are either true or false. In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0, respectively. Instead of elementary algebra, where the values of the variables are numbers and the prime operations are addition and multiplication, the main operations of Boolean logic, originally developed by George Boole in the mid 1800s, allows quite a few unexpected things to be mapped into bits and bytes. The great thing about Boolean logic is that, once you get the hang of things, Boolean logic (or at least the parts you need in order to understand the operations of computers) is outrageously simple.

George Boole, an English mathematician from the 19th century, developed an algebraic method that he first described in his 1847 book, The Mathematical Analysis of Logic and expounded upon in his An Investigation of the Laws of Thought (1854). In the world of boolean Algebra, AND logic corresponds to multiplication (*), and OR logic corresponds to addition (+). Because we want OR logic, we use addition in this case. Notice Excel is not case-sensitive, so we don't need to capitalize the colors. After the expression is evaluated, we have two arrays of TRUE and FALSE values like this: (mathematics, logic, computing) A system of symbolic logic that is the basis of Boolean algebra.

You start off with the idea that some statement P is either true or false, it can’t be anything in between (this called the law of the excluded middle). 2018-03-22
George Boole (/ buːl /; 2 November 1815 – 8 December 1864) was a largely self-taught English mathematician, philosopher and logician, most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Ireland. 2017-10-17
True or false (Boolean) conditions. The logical data type represents true or false states using the numbers 1 and 0, respectively.Certain MATLAB ® functions and operators return logical values to indicate fulfillment of a condition.

Or in more understandable language, it is studying the rules of logic when we're Apr 28, 2016 In Boolean logic statements can either be true or false (e.g. at the moment "I want a cup of tea" is false, but "I want a piece of cake" is always true), May 20, 2009 Boolean logic consists of three logical operators: OR; AND; NOT. Each operator can be visually described by using Venn diagrams, as shown Boolean logic conditions. Boolean And. If both values are true, the output is 1.
