1. Define NumPy and identify its role in the scientific Python ecosystem.
2. Explain why NumPy is significantly faster than standard Python loops using the concept of vectorization.
3. Execute installation commands for various environments including Pip, Conda, and Raspberry Pi.
4. Identify and interpret core ndarray attributes such as ndim, shape, and dtype.
5. Execute array creation and manipulation using functions like linspace, reshape, vstack, and hstack.
6. Apply elementwise operations, universal functions (ufuncs), and linear algebra solvers to numerical datasets.
7. Manage data precision and mitigate overflow errors using NumPy's scalar types and info tools (iinfo, finfo).
8. Implement flexible data ingestion from disk using genfromtxt with custom delimiters, headers, and column selections.
9. Apply General Broadcasting Rules to predict and control interactions between arrays of differing shapes.
10. Manage memory references and avoid "gotchas" in custom ndarray subclasses using the .base attribute.
