MRKL: An Arithmetic Expert
Intermediate
The problem, from first principles
MRKL's arithmetic expert exists because language models are unreliable at exact arithmetic. Sending a simple expression to a deterministic module gives an exact answer the language model can then report.
From theory to code
Implement arithmetic_expert(expr), evaluating a simple binary expression with +, - or *.
Constraints
- Return None for anything outside the supported form.
Hints
Hint 1
Match the expression with a regular expression that captures two numbers and an operator, then compute the result.
