## Gate Results

### D1 — Arithmetic

Command and expected → observed:

| Expression | Expected | Observed |
|---|---|---|
| `python calc.py "2+3*4"` | 14, exit 0 | `14`, exit 0 ✓ |
| `python calc.py "(2+3)*4"` | 20, exit 0 | `20`, exit 0 ✓ |
| `python calc.py "8-3-2"` | 3 | `3` ✓ (via unittest) |
| `python calc.py "-2+5"` | 3 | `3` ✓ (via unittest) |
| `python calc.py "2*-3"` | -6 | `-6` ✓ (via unittest) |

**D1: PASS**

### D2 — Division / EvalError

| Check | Expected | Observed |
|---|---|---|
| `python calc.py "7/2"` | 3.5, exit 0 | `3.5`, exit 0 ✓ |
| `python calc.py "1/0"` | error to stderr, exit non-zero | `error: division by zero` to stderr, exit 1 ✓ |
| `EvalError` raised (not `ZeroDivisionError`) | EvalError | confirmed by unittest ✓ |

**D2: PASS**

### D3 — Result type

| Expression | Expected type | Observed |
|---|---|---|
| `python calc.py "4/2"` | prints `2` (no `.0`) | `2` ✓ |
| `python calc.py "7/2"` | prints `3.5` | `3.5` ✓ |
| `calc("4/2")` returns `int` | `isinstance(result, int)` | True ✓ |
| `calc("7/2")` returns `float` | `isinstance(result, float)` | True ✓ |

**D3: PASS**

### D4 — CLI

| Command | Expected | Observed |
|---|---|---|
| `python calc.py "2+3*4"` | prints `14`, exit 0 | `14`, exit 0 ✓ |
| `python calc.py "1 +"` | error to stderr, exit non-zero | `error: unexpected end of input` to stderr, exit 1 ✓ |
| `python calc.py "1/0"` | error to stderr, exit non-zero | `error: division by zero` to stderr, exit 1 ✓ |

**D4: PASS**

### D5 — Full suite green, no regression

Command: `python -m unittest -q`
