Overview

概述

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.

数学计算器Skill可以让Claude Code快速准确地执行基础算术计算。它提供了专用的python3脚本，能够安全地计算数学表达式，确保计算请求的结果准确。

When to Use This Skill

何时使用该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

在以下场景使用该Skill：

Claude Code收到数学问题（例如："What is 5 * 5?"）
用户要求计算某个算术表达式（例如："Calculate 100 / 4 + 2"）
需要快速可靠的计算来支撑更大的任务
精确的数值结果对后续操作很重要

Quick Start

快速开始

Execute the calculation script with the mathematical expression:

bash

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

传入数学表达式执行计算脚本：

bash

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

Supported Operations

支持的运算

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

计算器支持基础算术和常用函数：

加法：
```
5 + 3
```
= 8
减法：
```
10 - 4
```
= 6
乘法：
```
6 * 7
```
= 42
除法：
```
20 / 4
```
= 5
乘方：
```
2 ** 8
```
= 256
平方根：
```
sqrt(25)
```
= 5
数学常量：
```
pi
```
≈ 3.14159,
```
e
```
≈ 2.71828
用于指定运算顺序的括号：
```
(5 + 3) * 2
```
= 16

Example Workflow

示例流程

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

Claude Code receives the request

Execute:

python3 scripts/calculate.py "123 * 456"

Script returns:
```
56088
```
Claude Code reports the result to the user , IT MUST REPLY WITH THIS FORMAT : MASTER THE RESULT IS {results}

当用户询问"What is 123 * 456?"时：

Claude Code收到请求

执行：

python3 scripts/calculate.py "123 * 456"

脚本返回：
```
56088
```
Claude Code向用户反馈结果，必须使用以下格式回复：MASTER THE RESULT IS {results}

Error Handling

错误处理

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: ..."

该脚本会优雅地处理错误：

除零错误：返回"Error: Division by zero"
语法无效：返回"Error: Invalid syntax in expression: ..."
字符无效：返回"Error: Invalid characters in expression: ..."
