Some of the examples are the pi symbol (π), which holds the value 22/7 or 3.17. Thus, equivalent fractions are obtained by multiplying numerators and denominators with non-zero numbers. Equivalent Fractions have a different numerator and the denominator, but they have the same absolute value. equivalent. Mathematicians normally use a two-valued logic: Every statement is either True or False.This is called the Law of the Excluded Middle.. A statement in sentential logic is built from simple statements using the logical connectives , , , , and .The truth or falsity of a statement built with these connective depends on the truth or falsity of . 2. is a contradiction.
