## Schema

| Column | Type | Description |
|--------|------|-------------|
| `id` | int | Unique row ID |
| `topic` | string | High-level topic |
| `difficulty` | string | easy or medium |
| `question` | string | The math problem |
| `answer` | string | Final answer |
| `reasoning` | string | Step-by-step explanation |
| `category` | string | Specific sub-type of problem |

## Example Rows

"What is 1900 / 5?" -> Answer: 380
Reasoning: "Divide: 1900 ÷ 5 = 380 because 5*380=1900."

"Solve for x: 12x + 15 = 87" -> Answer: 6
Reasoning: "Subtract 15 from both sides: 12x = 72. Then divide by 12: x = 6."

"What is 3/4 + 2/5?" -> Answer: "23/20"
Reasoning: "Common denominator 20. 3/4=15/20, 2/5=8/20. Sum = 23/20."

"What is the derivative of 7x^5 with respect to x?" -> Answer: "35x^4"
Reasoning: "Power rule: d/dx [x^n] = n*x^(n-1). So 7*5*x^4 = 35x^4."

## Intended Use

Built for instruction tuning and chain-of-thought training.

Recommended training format:
Input: {question}
Target: {reasoning} Answer: {answer}

Works for:
- Fine-tuning language models for math reasoning
- Teaching step-by-step problem solving
- Evaluating math capabilities
- Data augmentation alongside other math datasets
