# Math Calculator Skill This skill calculates mathematical expressions using shell commands. ## When to Use Use this skill when the user asks to evaluate a numeric expression, such as: - Basic arithmetic (add, subtract, multiply, divide) - Expressions with parentheses - Powers and square roots ## Method Pipe the expression into the `bc` (basic calculator) command: ```bash echo "(2 + 3) * 4" | bc # Output: 20 echo "2 ^ 10" | bc # Output: 1024 ``` For decimal results, set the scale first: ```bash echo "scale=2; 10 / 3" | bc # Output: 3.33 ``` ## Instructions 1. Translate the user's question into a single `bc` expression. 2. Run it with the `bash` tool: `echo "<expression>" | bc`. 3. Report the number printed by `bc` as the answer.
