📖 Full Retelling
Researchers in artificial intelligence have recently released a study titled “Chain of Thought in Order: Discovering Learning‑Friendly Orders for Arithmetic,” submitted to arXiv in June 2025. The paper investigates a previously overlooked aspect of transformer‑based reasoning systems: the sequence in which intermediate reasoning steps are presented. By exploring how different orders influence the difficulty of arithmetic problems, the authors aim to refine how these models process multi‑step mathematical tasks and improve downstream performance.
The study builds on the well‑established significance of intermediate steps in chain‑of‑thought prompting, but points out that the mere presence of steps is insufficient—how they are ordered can dramatically alter problem difficulty and the efficiency of reasoning. Through systematic experiments, the authors propose new frameworks for arranging reasoning steps that yield more learnable sequences, potentially enhancing transformer performance on arithmetic benchmarks and informing future educational and AI‑model design in multi‑step reasoning contexts.

Abstract: The chain of thought, i.e., step-by-step reasoning, is one of the fundamental mechanisms of Transformers. While the design of intermediate reasoning steps has been extensively studied and shown to critically influence performance on mathematical, multi-step reasoning tasks, the ordering of these steps has received little attention, despite its significant effect on the difficulty of reasoning. This study addresses a novel task of unravel
