# Mathematical Operations

> Have the model call math functions for reliable calculations

### Basic Calculator Functions

Let’s start off simple. While you wouldn’t typically use the API just for math, it clearly shows how Incredible can execute precise operations beyond plain text generation.

```bash
curl https://api.incredible.one/v1/chat-completion \
  --header "Content-Type: application/json" \
  --data '{
    "model": "small-1",
    "functions": [
      {
        "name": "calculate",
        "description": "Perform mathematical calculations with high precision",
        "parameters": {
          "type": "object",
          "properties": {
            "expression": {
              "type": "string",
              "description": "Mathematical expression to evaluate (e.g., '\''2 + 2'\'')"
            }
          },
          "required": ["expression"]
        }
      }
    ],
    "messages": [
      {
        "role": "user",
        "content": "Calculate the compound interest on $10,000 at 5% annual rate for 3 years"
      }
    ]
  }
```

### Example Scenarios

1. **User:** “What’s 25 × 4?”\
   → AI calls calculate with `expression="25 * 4"`\
   **AI:** “The answer is 100.”

2. **User:** “What is (50 + 20) ÷ 7?”\
   → AI calls calculate with `expression="(50 + 20) / 7"`\
   **AI:** “The result is 10.”

3. **User:** “Find the square root of 144.”\
   → AI calls calculate with `expression="sqrt(144)"`\
   **AI:** “The square root is 12.”

4. **User:** “How much is 15% of 200?”\
   → AI calls calculate with `expression="200 * 0.15"`\
   **AI:** “The answer is 30.”
