Sep 25, 2023 · Description. Logical AND ( &&) evaluates operands from left to right, returning immediately with the value of the first falsy operand it encounters; if all values are truthy, the value of the last operand is returned. If a value can be converted to true, the value is so-called truthy. If a value can be converted to false, the value is so-called ...
Sep 25, 2023 · The logical OR (||) (logical disjunction) operator for a set of operands is true if and only if one or more of its operands is true. It is typically used with boolean (logical) values. When it is, it returns a Boolean value. However, the || operator actually returns the value of one of the specified operands, so if this operator is used with non-Boolean values, it will return a non-Boolean value.
Examples Using Set Theory. In set theory, ‘and’ and ‘or’ can drastically change outcomes. For example, let’s consider two sets A = {1, 2} and B = {2, 3}. The intersection of these sets (A AND B) results in a new set containing elements common to both original sets – here it is {2}. But side lies union operation that symbolizes OR.

Mar 7, 2019 · 26. The logical "and" is ∧ ∧ (and the corresponding "or" is ∨ ∨ ). Let me note that, unless you are actually talking about formal logic (or set theory, etc.), most people never use this symbol to mean "and" in "ordinary" mathematics.
VIDEO ANSWER: Okay, so we're asked to discuss the equivalences among our conditional, converse, inverse, and contrapositive. So I'm going to create…
