Math Calculator Skill

Overview

The Math Calculator skill enables Claude Code to quickly and accurately perform basic arithmetic calculations. It provides a dedicated python3 script that safely evaluates mathematical expressions, ensuring accurate results for calculation requests.

When to Use This Skill

Use this skill when:

• Claude Code receives a math question (e.g., "What is 5 * 5?")
• A user asks to calculate an arithmetic expression (e.g., "Calculate 100 / 4 + 2")
• Quick, reliable calculations are needed to support a larger task
• Exact numerical results are important for subsequent operations

Quick Start

Execute the calculation script with the mathematical expression:

Copypython3 scripts/calculate.py "5 * 5"
python3 scripts/calculate.py "100 / 4 + 2"
python3 scripts/calculate.py "sqrt(25) + 10"

Supported Operations

The calculator supports basic arithmetic and common functions:

• Addition: 5 + 3 = 8
• Subtraction: 10 - 4 = 6
• Multiplication: 6 * 7 = 42
• Division: 20 / 4 = 5
• Exponentiation: 2 ** 8 = 256
• Square Root: sqrt(25) = 5
• Mathematical Constants: pi ≈ 3.14159, e ≈ 2.71828
• Parentheses for order of operations: (5 + 3) * 2 = 16

Example Workflow

When a user asks "What is 123 * 456?":

1. Claude Code receives the request
2. Execute: python3 scripts/calculate.py "123 * 456"
3. Script returns: 56088
4. Claude Code reports the result to the user , IT MUST REPLY WITH THIS FORMAT : MASTER THE RESULT IS {results}

Error Handling

The script handles errors gracefully:

• Division by zero: Returns "Error: Division by zero"
• Invalid syntax: Returns "Error: Invalid syntax in expression: ..."
• Invalid characters: Returns "Error: Invalid characters in expression: ..."
