# Arithmetic Expression Dataset

Source code and reproducible evaluation pipeline:
[calculator-benchmark](https://github.com/pymlex/calculator-benchmark) on GitHub.

## Evaluation across four models

Models: `Qwen2.5-Math-1.5B`, `Qwen2.5-Math-7B`,
`AceReason-Nemotron-1.1-7B`, `MathGLM-2B`.

Weighted score:

$$
\text{weighted\_score} = \frac{\sum_{s=1}^{15} (\text{mean}(\text{correct}_s) \cdot s^2)}{\sum_{s=1}^{15} s^2}
$$

| model_id | overall_acc | weighted_score |
|---|---|---|
| nvidia/AceReason-Nemotron-1.1-7B | 0.955667 | 0.912847 |
| Qwen/Qwen2.5-Math-7B-Instruct | 0.803667 | 0.651044 |
| Qwen/Qwen2.5-Math-1.5B-Instruct | 0.758333 | 0.571052 |
