Original: Notably, chain of thought (CoT) prompting,a recent technique for eliciting complex multi-step reasoning through step-bystep answer examples, achieved the state-of-the-art performances in arithmeticsand symbolic reasoning, difficult system-2 tasks that do not follow the standardscaling laws for LLMs.

Original: While these successes are often attributed to LLMs’ability for few-shot learning, we show that LLMs are decent zero-shot reasonersby simply adding “Let’s think step by step” before each answer.
