    Vector

    A mathematical object with magnitude and direction, often represented as an arrow. Think of it like the force of a push or pull.

    Mathematical Induction

    Prove something by starting with a general statement then applying it to specific cases.

    Function

    A function is like a machine that takes an input and produces an output. Different inputs can produce the same output. The function tells you the rule for what comes out.

    Matrix

    An array of numbers used to represent linear transformations and systems of equations. Think of it as a set of numbers organized in rows and columns.
