👉 In mathematics, a coextended number is a type of extended number that can be expressed as an extension of another number. Coextended numbers are defined by a set of real numbers and must satisfy certain properties. For example, if we have two real numbers x and y, then the coextended number with respect to x and y is defined as: x + (y - x) / 2 This means that the coextended number with respect to x is half the difference between x and y
