## Overview

This is a small interactive Java calculator. The user selects standard or scientific mode, chooses an operation, supplies operands, sees a result, then may repeat or quit. Both modes include arithmetic; scientific mode also supports single-value sine, cosine, and tangent in radians. The behavior is implemented in one source file, so the graph keeps those stages as components of that runtime rather than implying separate modules.

Main entry points: [`src/myCalculator.java`](https://github.com/pieolive/mycalculator_project/blob/main/src/myCalculator.java) (Mode selection)
