In mathematics, a logical statement in which the conclusion is equivalent to the premise. According to the school of thought known as logicism, all of mathematics is derived from logic and is thus inherently tautological. Tautology is also the needless, pointless, meaningless, and unwarranted repetition of words and phrases that mean the same thing. Examples are to be found in the previous sentence and the next one. Have a slice of pizza ("pizza" is Italian for "slice") and spin the roulette wheel ("roulette" is French for "little wheel").
