Arithmetic chain
what this tests
Evaluate a short arithmetic chain strictly left to right, ignoring operator precedence, as the prompt instructs.
Tests two things at once: multi-step carry-the-value arithmetic, and whether the agent follows an explicit rule (no precedence) that contradicts its training prior.
Grading: First numeric token must equal the server-computed result.
sample instance · fixed demo seed, never used in live runs
Compute step by step, left to right (no operator precedence): 23 * 5 + 8 / 3 - 2. Answer with just the final number.
Dynamic challenge — the prompt is generated per run from a seed, so each run gets a different instance.
