# StreetMath Dataset
## Dataset Summary
The **Street Math dataset** is a synthetic reasoning benchmark that evaluates a model’s ability to **approximate sums of decimal prices** in everyday shopping scenarios.
Each example presents a list of item prices, and the model must select the approximate total cost (before tax) from multiple-choice options.
The dataset is designed to test **numerical reasoning, estimation, and handling of decimal numbers**.
Language: **English**.
Domain: **mathematics applied to real-world shopping tasks**.
## Languages
- **English (en)**: prompts and options are written in plain English, with U.S. dollar formatting for prices.
## Data Instances
Example instance:
```json
{
"id": "basket_sum_000243",
"topic": "basket_sum",
"subtopic": "decimal_prices",
"prompt": "You’re buying these items: $3.55, $15.42, $4.56, $12.63, $6.08. About how much will you pay (before tax)?",
"labels": ["A", "B", "C", "D"],
"correct_label": "A",
"choices": ["$43.00", "$14.11", "$42.24", "$182.80"],
"correct_option": 0,
"metadata": {
"exact_value": 42.24,
"good_value": 43.0,
"mild_value": 14.11,
"way_value": 182.8,
"prices": [3.55, 15.42, 4.56, 12.63, 6.08]
},
"split": "test"
}
```
## Intended Uses
The Basket Sum dataset is intended for:
- **Benchmarking language models** on basic numerical reasoning and arithmetic in natural language contexts.
- **Evaluating estimation skills**: testing whether models can provide approximate answers rather than exact calculations.
- **Educational and research purposes**: studying how models handle everyday math tasks such as adding decimal prices.
This dataset is **not** intended for:
- Financial or accounting applications.
- Real-world shopping or economic forecasting.
- Any critical decision-making where incorrect numerical outputs could cause harm.
## Format
- **File type:** JSON Lines (`.jsonl`)
- **Each line:** one example as a JSON object
- **Compatible with:** Hugging Face `datasets` library (`load_dataset("json", data_files="...")`)
## How to Get the Dataset
You can easily load this dataset from the Hugging Face Hub using the `datasets` library:
```python
from datasets import load_dataset
# Load the dataset
dataset = load_dataset("Chiung-Yi/StreetMath")
# Access the test split
test_dataset = dataset["test"]
# Example: print the first item
print(test_dataset[0])
```
