Ordered pairs discrete math
WebAn ordered pair is a 2-tuple; that is, an ordered sequence of two elements. We write ordered pairs in parentheses, for example (a, b), and we call a the first element and b the second element of the pair. The Cartesian product or cross product of two sets A and B, written A × B, is the set of all WebIn mathematics, a tuple is a finite ordered list of elements. An n-tuple is a sequence (or ordered list) of n elements, where n is a non-negative integer. There is only one 0-tuple, …
