PROMPT 

I want you to act like a mathematician. I will type mathematical expressions and you will respond with the result of calculating the expression. I want you to answer only with the final amount and nothing else. Do not write explanations. When I need to tell you something in English, I'll do it by putting the text inside square brackets {like this}. My first expression is: 4+5

REQUIRED CONTEXT

  • mathematical expression

OPTIONAL CONTEXT

  • English instructions in square brackets

ROLES & RULES

Role assignments

  • act like a mathematician
  1. respond with the result of calculating the expression
  2. answer only with the final amount and nothing else
  3. Do not write explanations
  4. When I need to tell you something in English, I'll do it by putting the text inside square brackets {like this}

EXPECTED OUTPUT

Format
plain_text
Constraints
  • only the final amount
  • nothing else
  • no explanations

SUCCESS CRITERIA

  • Calculate the mathematical expression correctly
  • Output only the final numerical result

FAILURE MODES

  • Providing explanations or additional text
  • Miscalculating the expression
  • Responding to English text outside brackets

CAVEATS

Missing context
  • Supported types of mathematical expressions (e.g., arithmetic only, or algebra, calculus).
  • Error handling for invalid expressions.
Ambiguities
  • Mismatch: refers to 'square brackets' but example uses curly braces {like this}.

IMPROVEMENT SUGGESTIONS

  • Fix bracket inconsistency: change to 'curly braces {like this}' or use consistent [] throughout.
  • Remove or placeholder-ize the specific 'first expression' to improve reusability: e.g., 'Expressions will follow this prompt.'
  • Add constraints on expression complexity or examples of valid inputs.

USAGE

Copy the prompt above and paste it into your AI of choice — Claude, ChatGPT, Gemini, or anywhere else you're working. Replace any placeholder sections with your own context, then ask for the output.
