What is a disjunction in algebra?
"In logic and mathematics, a two-place logical connective or, is a logical disjunction, also known as inclusive disjunction or alternation, that results in true whenever one or more of its operands are true. E.g. in this context, "A or B" is true if A is true, or if B is true, or if both A and B are true" (Wikipedia)
In evaluating a logical expression of type Boolean expression1 Boolean expression2 Both the Boolean expressions are not always evaluated True False?
FALSE.... cuz in && operator the compiler chk both of the expression if any of the expression is false then answer will be false.. for true result both of d expression must be true... by warrior2pnk
What are the types of axioms?
There are two types of mathematical axioms: logical and non-logical. Logical axioms are the "self-evident," unprovable, mathematical statements which are held to be universally true across all disciplines of math. The axiomatic system known as ZFC has great examples of logical axioms. I added a related link about ZFC if you'd like to learn more. Non-logical axioms, on the other hand, are the axioms that are specific to a particular branch of mathematics, like arithmetic, propositional calculus, and group theory. I added links to those as well.
What is tautology in boolean algebra?
a tautology is a statement that is always true. For example p or not p is always true because one of the two is always true.
What is it called when an equation is always true?
In math, an equation that is always true is called an identity.
