## Why it matters

Extends algebra to complex numbers, exponentials and conics; the algebraic machinery needed for calculus and physics modeling.

## Where it is used

Compound interest, exponential growth/decay models, orbital conic sections, signal representation.

## How you know you have learned it

Complete 3 independent examples correctly + explain common failure modes.
