+## 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
