# Function simplifyCore simplifyCore() performs single pass simplification suitable for applications requiring ultimate performance. In contrast, simplify() extends simplifyCore() with additional passes to provide deeper simplification. ## Syntax ```js simplifyCore(expr) ``` ### Parameters Parameter | Type | Description --------- | ---- | ----------- `node` | Node | The expression to be simplified `options` | Object | Simplification options, as per simplify() ### Returns Type | Description ---- | ----------- Node | Returns expression with basic simplifications applied ### Throws Type | Description ---- | ----------- ## Examples ```js const f = math.parse('2 * 1 * x ^ (2 - 1)') math.simpifyCore(f) // Node {2 * x} math.simplify('2 * 1 * x ^ (2 - 1)', [math.simplifyCore]) // Node {2 * x} ``` ## See also [simplify](simplify.md), [resolve](resolve.md), [derivative](derivative.md)
