### Mathematical Expression

Sequences: separate equations with semicolons (e.g., "x+1=3; 2*x=4")

### Equation Operations

Single equations: operations replace the equation.
Sequences: operations add new steps.

Automatically Simplify after operations

### Function Operations

Apply functions to both sides of equations.

### Evaluate Expression

Provide variable values (e.g., x=2, y=3). For equations, this will check if the solution is correct.
