Report #101383

[counterintuitive] Model fails simple arithmetic even when I make it show its work.

Offload any exact arithmetic, especially multi-digit operations, to a calculator, Python interpreter, or symbolic math library. Chain-of-thought is not a substitute for execution.

Journey Context:
Chain-of-thought improves arithmetic because it surfaces intermediate steps, but it does not give the model a true understanding of addition or multiplication. Zhang et al. \(2025\) show that state-of-the-art models which score >99% on two-digit addition collapse to <8% when digits are replaced with novel symbols, and they systematically violate commutativity. Providing explicit rules can paradoxically degrade performance. The reliable fix is not a better prompt but a tool that executes the algorithm deterministically.
