Title: [Understand, Solve and Translate: Bridging the Multilingual Mathematical Reasoning Gap](https://www.arxiv.org/abs/2501.02448)

Large language models (LLMs) demonstrate exceptional performance on complex reasoning tasks. However, despite their strong reasoning capabilities in high-resource languages (e.g., English and Chinese), a significant performance gap persists in other languages. To investigate this gap in Korean, we introduce HRM8K, a benchmark comprising 8,011 English-Korean parallel bilingual math problems. Through systematic analysis of model behaviors, we identify a key finding: these performance disparities stem primarily from difficulties in comprehending non-English inputs, rather than limitations in reasoning capabilities. Based on these findings, we propose UST (Understand, Solve, and Translate), a method that strategically uses English as an anchor for reasoning and solution generation. By fine-tuning the model on 130k synthetically generated data points, UST achieves a 10.91% improvement on the HRM8K benchmark and reduces the multilingual performance gap from 11.6% to 0.7%. Additionally, we show that improvements from UST generalize effectively to different Korean domains, demonstrating that capabilities acquired from machine-verifiable content can be generalized to other areas. We publicly release the benchmark, training dataset, and models.

### Groups and and Tasks

#### Groups

* `hrm8k`: HRM8K comprises 8,011 instances for evaluation, sourced through a combination of translations from established English benchmarks (e.g., GSM8K, MATH, OmniMath, MMMLU) and original problems curated from existing Korean math exams. This benchmark consists of Korean instruction and question.
* `hrm8k_en`: English version of `hrm8k`. This benchmark consists of English instruction and question.

#### Tasks

* `hrm8k_{gsm8k|ksm|math|mmmlu|omni_math}`
* `hrm8k_en_{gsm8k|ksm|math|mmmlu|omni_math}`

### Checklist
