larr
Displays a leftward-pointing arrow commonly used to indicate direction, implication, or mapping relationships.
Overview
Essential for mathematical notation and technical writing where left-directed relationships need to be shown visually.
- Frequently used in set theory and abstract algebra to denote mappings or transformations
- Common in computer science for indicating previous steps or reverse operations
- Appears in logic and proof writing to show reverse implications
- Often employed in documentation and technical diagrams to indicate navigation or flow
- Useful in expressing mathematical concepts like inverse functions or reverse relationships
Examples
Showing logical implication from right to left.
q \larr p \text{ means } p \text{ implies } qIndicating a reverse mapping between sets.
B \larr ARepresenting backward assignment in algorithms or programming.
