Scientific Calculator.
A scientific calculator widget that evaluates every expression through a real maths engine (mathjs, BigNumber precision) — never the model's mental arithmetic. In-app it maps to an evaluate MCP tool: the model reads back a deterministically computed result.

User value
Two jobs: (1) a genuinely useful calculator; (2) it removes the "catch the LLM out on maths" failure mode entirely — 0.1+0.2, big factorials, operator precedence all return exact, because computation is delegated, not guessed.
From project input to reviewed output.
The page explains the workflow, identifies the information required and routes the user into Adelphos for the complete task.
Adelphos workflow
Provide the brief and source information, confirm the required output, run the applicable named tools, then review the result and resolve assumptions before use.
The user is responsible for verifying all inputs, assumptions, standards, selections, outputs and suitability, and for obtaining competent-person review. Adelphos accepts no responsibility for decisions made using this calculation.
Frequently asked questions.
What is 20 factorial?
20 factorial is 20 multiplied by every positive integer below it, which equals 2,432,902,008,176,640,000. The scientific calculator returns the evaluated result together with the submitted expression and calculation record.
Does this calculator do order of operations?
Yes. The safe expression evaluator applies parentheses, powers, multiplication and division, then addition and subtraction in the correct order. It accepts the supported mathematical functions shown by the calculator and does not execute arbitrary code.

How do I use Scientific Calculator?
Open Adelphos Chat with the project brief and relevant source files. Adelphos will identify the required inputs, run the applicable workflow and present the output for review.
Can an AI agent use this through MCP?
Where the workflow exposes a named MCP tool, an authorised agent can submit the structured inputs and receive the same traceable result. Consequential outputs remain subject to user review.
