[27] Being able to rely on not only two parents but grandparents, aunts, uncles, brothers, and sisters helps to create a support system which in turn brings families closer together. Living in an extended family provides many things that a nuclear family does not.
Extension of a line segment (finite) into an infinite line (e.g., extended base) Exterior algebra, Grassmann's theory of extension, in geometry; Field extension, in Galois theory; Group extension, in abstract algebra and homological algebra; Homotopy extension property, in topology; Kolmogorov extension theorem, in probability theory
Extended reality (XR) is an umbrella term to refer to augmented reality (AR), mixed reality (MR), and virtual reality (VR). The technology is intended to combine or mirror the physical world with a " digital twin world" able to interact with it, [ 1 ] [ 2 ] giving users an immersive experience by being in a virtual or augmented environment.

The children's mother is not necessarily the wife of one of the children's fathers."
The Extended Mind" by Andy Clark and David Chalmers (1998) [4] is the paper that originally stated the EMT. Clark and Chalmers present the idea of active externalism (not to be confused with semantic externalism ), in which objects within the environment function as a part of the mind.

In mathematics, the extended real number system [a] is obtained from the real number system by adding two elements denoted + and [b] that are respectively greater and lower than every real number. This allows for treating the potential infinities of infinitely increasing sequences and infinitely decreasing series as actual infinities .
Extended-play vinyl record of Michael Nesmith's "I Fall to Pieces" with four tracks. An extended play (EP) is a musical recording that contains more tracks than a single but fewer than an album. [1] Contemporary EPs generally contain up to eight tracks and have a playing time of 15 to 30 minutes. [7]
