INeedCalc-calculators

By Syed Haris 👁 61 views ▲ 0 votes

Gives your agent exact, deterministic calculators instead of letting the model do mental maths. Includes AP score predictors (World History, Calculus AB, English Language, Seminar, AP Physics 1, AP Research), an Australian contractor pay vs salary converter (super, billable days, GST threshold, break-even rate), and an alcohol dilution calculator. Every result links to the matching web calculator. No API keys, runs locally.

# Multicule Calculators for OpenClaw

Deterministic calculator tools for OpenClaw agents. Instead of the model doing arithmetic in its head (and occasionally getting it wrong), your agent calls a tool and gets an exact, structured answer.

Built by [Multicule](https://multicule.com), a collection of free online calculators.

## Tools

| Tool | What it does |
|---|---|
| `multicule_ap_world_history_score` | Predicts an AP World History: Modern score (1–5) from MCQ, SAQ, DBQ and LEQ results |
| `multicule_ap_calculus_ab_score` | Predicts an AP Calculus AB score from MCQ and FRQ points |
| `multicule_ap_english_language_score` | Predicts an AP Lang score from MCQ and the three essay scores |
| `multicule_ap_physics_1_score` | Predicts an AP Physics 1 score from MCQ and the four FRQ types |
| `multicule_ap_seminar_score` | Predicts an AP Seminar score from both performance tasks and the exam |
| `multicule_ap_research_score` | Predicts an AP Research score from the academic paper and oral defense |
| `multicule_contractor_pay` | Converts an Australian contractor hourly/daily rate into an equivalent salary (super, billable days, GST threshold, break-even vs a salary offer) |
| `multicule_alcohol_dilution` | Calculates how much water to add to reach a target ABV |

Every result includes a link to the matching web calculator so users can double-check or explore further.

- [Contractor pay calculator (Australia)](https://multicule.com/contractor-pay-calculator/)
- [Alcohol dilution calculator](https://multicule.com/alcohol-dilution-calculator/)

## Install

```bash
openclaw plugins install clawhub:openclaw-multicule-calculators
```

No configuration or API keys needed. Everything runs locally.

## Example prompts

- "I got 40/55 on MCQ, 6 on SAQs, 5 on the DBQ and 4 on the LEQ. What AP World score is that?"
- "I've been offered $67/hour as a contractor in Sydney. How does that compare to a $100k salary?"
- "How much water do I add to 1 litre of 60% spirit to get 40%?"

## Notes

- AP predictions are estimates. The College Board sets score cutoffs each year; these use recent historical ranges.
- Contractor figures are before tax, insurance and business costs. Defaults: 7.6 hours/day, 220 billable days, 12% super.

## Development

Requires Node 24.16+ and OpenClaw 2026.5.17+.

```bash
npm install
npm run plugin:validate
openclaw plugins install ./
openclaw plugins inspect multicule-calculators --runtime
```
