## Overview

Batch-Calculator is a single-file interactive terminal calculator. The user supplies a count and comma-separated integers, then chooses one of eleven operations (or exits); the script validates the count, dispatches the selection, and prints the result. All calculation routines and the terminal menu live in main.py, with no separate storage or service layer. The README and sampled source show no other product subsystems.

Main entry points: [`main.py`](https://github.com/mrmaker53/batch-calculator/blob/main/main.py) (Operation Dispatch)
