Install and run

Setup complexity: low.

clawhub skill install s17cmvaw2cy01v6y6fpq1h7yts84k0r0:cn-math-calculator

Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

Run-check

$0.02 USD

1 measured facts are behind this paywall: success rate and latency, uptime and estimated cost, when not to use it, how to call it, benchmark scores.

Agents pay $0.02 in USDC. A card payment is $0.50, the smallest a card allows.

# 数学计算器

数学表达式计算器。支持基本运算、科学计算。

## 功能

- 四则运算 + - * / ^(幂) %(取模)
- 科学函数：sin, cos, tan, log, sqrt, abs
- 常量：pi, e
- 表达式安全求值（不使用eval）
- 纯本地处理，无需API

## 使用方法

```bash
python3 scripts/math_calculator.py "2+3*4"
python3 scripts/math_calculator.py "sqrt(144)"
python3 scripts/math_calculator.py "sin(pi/2)"
```

## 示例

输入：`2+3*4` → 输出：`结果: 14.0`

## Description:

Cn Math Calculator helps agents safely evaluate mathematical expressions and convert common units for Chinese-language math workflows.

This skill is ready for commercial/non-commercial use.

## Publisher:

[freedompixels](https://clawhub.ai/user/freedompixels)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and agents use this skill to calculate arithmetic and scientific expressions, return optional JSON results, and perform common length, weight, temperature, and area conversions with Chinese and English unit names.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Untrusted public input could submit very long expressions, very large numeric operations, or calculations that take excessive execution time.

Mitigation: Use expression length, numeric-size, and execution-time limits before exposing the calculator to public traffic.

## Reference(s):

- [ClawHub skill page](https://clawhub.ai/freedompixels/skills/cn-math-calculator)

## Skill Output:

**Output Type(s):** [text, JSON, shell commands, guidance]

**Output Format:** [Plain text or JSON, often with inline shell commands]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Runs locally with Python standard library math evaluation and unit conversion logic.]

## Skill Version(s):

1.3.2 (source: server release evidence)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
