Editing Almost all (section)

{{Short description|In mathematics, with negligible exceptions}}
In [[mathematics]], the term "'''almost all'''" means "all but a negligible quantity". More precisely, if <math>X</math> is a [[set (mathematics)|set]], "almost all elements of <math>X</math>" means "all elements of <math>X</math> but those in a [[negligible set|negligible]] [[subset]] of <math>X</math>". The meaning of "negligible" depends on the mathematical context; for instance, it can mean [[finite set|finite]], [[countable set|countable]], or [[null set|null]].

In contrast, "'''almost no'''" means "a negligible quantity"; that is, "almost no elements of <math>X</math>" means "a negligible quantity of elements of <math>X</math>".
