Ordered pair of real numbers
In mathematics, an ordered pair (a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b. (In contrast, the unordered pair {a, b} equals the unordered pair {b, a}.) Ordered pairs are also called 2-tuples, or … See more Let $${\displaystyle (a_{1},b_{1})}$$ and $${\displaystyle (a_{2},b_{2})}$$ be ordered pairs.

WebA complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written \,a+bi\, where \,a\, is the real part and \,b\, is the imaginary part. For example, \,5+2i\, is a complex number. So, too, is \,3+4i\sqrt {3}. Imaginary numbers differ from real numbers in that a squared imaginary ...
