A Survey of Multimodal Mathematical Reasoning: From Perception, Alignment to Reasoning
Pith reviewed 2026-05-15 14:48 UTC · model grok-4.3
The pith
Multimodal mathematical reasoning approaches are reviewed through four questions on extraction, alignment, reasoning and evaluation.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The central claim is that a systematic review organized around four fundamental questions—what to extract from multimodal inputs, how to represent and align textual and visual information, how to perform the reasoning, and how to evaluate the correctness of the overall reasoning process—establishes a clear roadmap for understanding and comparing different multimodal mathematical reasoning approaches.
What carries the argument
The four fundamental questions that organize the review of multimodal mathematical reasoning approaches and serve as the framework for categorizing perception, alignment, reasoning and evaluation methods.
Load-bearing premise
That all relevant multimodal mathematical reasoning approaches fit neatly into the four questions without major omissions or uncategorizable new methods.
What would settle it
A substantial set of recent papers on multimodal math reasoning whose techniques cannot be placed under any of the four questions on extraction, alignment, reasoning and evaluation.
read the original abstract
Multimodal Mathematical Reasoning (MMR) has recently attracted increasing attention for its capability to solve mathematical problems involving both textual and visual modalities. However, current models still face significant challenges in real-world visual math tasks, often misinterpreting diagrams, failing to align mathematical symbols with visual evidence, or producing inconsistent reasoning steps. Moreover, existing evaluations mainly focus on checking final answers rather than verifying the correctness or executability of each intermediate step. A growing body of recent research addresses these issues by integrating structured perception, explicit alignment, and verifiable reasoning within unified frameworks. To establish a clear roadmap for understanding and comparing different MMR approaches, we systematically review them around four fundamental questions: (1) What to extract from multimodal inputs, (2) How to represent and align textual and visual information, (3) How to perform the reasoning, and (4) How to evaluate the correctness of the overall reasoning process. Finally, we discuss open challenges and share our thoughts on future research directions.

Referee Report
Summary. The manuscript is a survey of Multimodal Mathematical Reasoning (MMR) that organizes existing literature around four questions: (1) what to extract from multimodal inputs, (2) how to represent and align textual and visual information, (3) how to perform the reasoning, and (4) how to evaluate the correctness of the overall reasoning process. It reviews challenges such as diagram misinterpretation and inconsistent steps, highlights recent work on structured perception and verifiable reasoning, and concludes with open challenges and future directions.
Significance. If the four-question framework proves useful as a descriptive lens, the survey offers a clear comparative roadmap for MMR methods, helping researchers map progress in perception, alignment, and step-wise evaluation rather than final-answer checking alone. This structure could usefully highlight gaps in handling visual math symbols and executable reasoning chains.
major comments (1)
- [Abstract and §1] The central organizing claim (abstract and §1) that the four questions yield a systematic roadmap assumes they partition the literature without major omissions, yet the manuscript provides no explicit discussion or table of boundary cases (e.g., end-to-end models that entangle extraction and reasoning) or a completeness argument for the covered papers.
minor comments (2)
- A summary table mapping representative papers to the four categories would improve readability and allow quick comparison of approaches.
- Ensure all cited works include publication years and venues in the reference list for a fast-moving field.
Simulated Author's Rebuttal
We thank the referee for the constructive feedback. We agree that explicitly addressing boundary cases and providing a completeness argument will strengthen the organizing framework in the abstract and §1. We will revise the manuscript accordingly.

Referee: [Abstract and §1] The central organizing claim (abstract and §1) that the four questions yield a systematic roadmap assumes they partition the literature without major omissions, yet the manuscript provides no explicit discussion or table of boundary cases (e.g., end-to-end models that entangle extraction and reasoning) or a completeness argument for the covered papers.
Authors: We appreciate this observation. Our four-question framework is intended as a descriptive lens rather than a strict partition, but we acknowledge the value of discussing boundary cases such as fully end-to-end models that entangle perception, alignment, and reasoning. We will add a dedicated paragraph in §1 (and a small summary table) that explicitly identifies such models from the surveyed literature, explains how they map onto (or deviate from) the four questions, and outlines the literature-search criteria (keywords, venues, time window, and inclusion rules) used to argue for reasonable coverage of major MMR works. This revision will make the roadmap claim more robust without altering the overall structure. revision: yes
Circularity Check
No significant circularity in survey structure
full rationale
This is a literature survey whose central contribution is a descriptive organizational framework mapping existing MMR papers onto four questions (perception/extraction, representation/alignment, reasoning, evaluation). No original derivations, equations, predictions, fitted parameters, or theorems are presented that could reduce to inputs by construction. The four-question structure is offered as a comparative lens rather than a uniqueness theorem or exhaustive partition; boundary cases are acknowledged as standard for surveys. Any self-citations serve only to reference prior work and are not load-bearing for novel claims.
