A long expression refers to a sequence of symbols that represents a computation or a statement. In programming and mathematics, expressions are fundamental building blocks. A long expression is typically characterized by its extensive length, often involving multiple operators, operands, and function calls. The readability and maintainability of code can be significantly impacted by the presence of excessively long expressions.

In programming, long expressions can arise from complex calculations, nested conditional statements, or lengthy method chains. While sometimes unavoidable, they can make it difficult for developers to understand the logic, debug errors, or modify the code. Refactoring techniques, such as breaking down a long expression into smaller, named variables or intermediate functions, are often employed to improve clarity.

The exact definition of "long" is subjective and can depend on coding style guides, team conventions, and the complexity of the domain. However, many style guides suggest limiting line lengths to improve readability. When an expression exceeds these limits, it might be considered too long. In mathematical contexts, long expressions can represent intricate formulas or derivations, and simplification or algebraic manipulation is often used to make them more manageable. The goal in both fields is to balance expressiveness with clarity.
