1. The user requests that answers must be numbers. 2. This means all solutions should be presented as numerical values, not expressions or variables. 3. For example, if solving $x^2=4$, the answers should be $2$ and $-2$, not $\pm 2$ or $\sqrt{4}$. 4. Always simplify and calculate to provide final numeric answers. 5. This ensures clarity and meets the user's requirement for numeric solutions.
