# 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.
