Booleans are to [-258] what [48l integers] are to [-arithmetic].]\n\nIn formal [-258], a boolean variable is a [-variable] that can take on one of only two possible values: "[-true]" or "[-false]". [2v8] can then be said to [-evaluation evaluate] to one of these two values, in the same way that ordinary [algebra algebraic] expressions evaluate to a [-54y].\n\nAlso as in algebraic expressions, boolean values can be manipulated using certain operators such as [and_operator $\\land$ (and)], [or_operator $\\lor$ (or)], [negation_operator $\\neg$ ([negation)], and [implication_operator $\\rightarrow$ (implication)]. This field is called, surprisingly, [-boolean_algebra].\n\nBecause booleans can only express [4mq absolute truth or falsity], when working with measures of uncertainty you must use other
