The letters lim with an arrow beneath, naming a value approached.
Also known as: Limit, Lim notation, Tends to notation
Limit notation names the value a function approaches as its input approaches something, which is not the same as the value at that point. The arrow beneath carries the whole condition, and a superscript plus or minus on the target restricts the approach to one side.
Names the value a function approaches as its argument approaches the value written under the arrow.
Contexts: Mathematics
Describes behaviour near a point rather than at it, so a limit can exist where the function is undefined.

Takes a superscript plus or minus on the target to restrict the approach to one side, which is how one-sided limits are written.
