## simplifyCore(): Core Symbolic Simplification

**simplifyCore()** applies core algebraic simplification rules to an expression. It can reduce redundant operations and normalize forms before evaluation or display.

## Use symbolic tools deliberately

Compare it with [simplify()](https://calcul.io/function/simplify/index.md) and [simplifyConstant()](https://calcul.io/function/simplifyConstant/index.md). Equivalent expressions can have different desired forms, so verify results with [evaluate()](https://calcul.io/function/evaluate/index.md) using representative values.

Simplification is not a substitute for domain checks: cancelling factors can hide exclusions such as division by zero. Use [parse()](https://calcul.io/function/parse/index.md) to inspect an expression before transforming it.
