Self-Consistency Voting: Have AI Solve the Same Problem Three Times and Take the Consensus

Self-Consistency is an advanced technique validated as effective in 2026 (it shows a significant improvement over single-path reasoning on GSM8K math problems). The principle is to run multiple reasoning paths and take a majority vote, which cancels out the occasional arithmetic slip a single path might make. Most people don't realize they can do this manually, so this prompt packages it as a no-code version — the AI runs the calculation three separate ways within a single reply, then votes on the result. It's aimed at everyday Taiwan scenarios where a wrong answer is costly: tax estimates, comparing monthly loan payments, scaling a recipe, or splitting a bill. The real value is in the fourth step — when the three paths disagree, it flags this itself and says 'there's a discrepancy here, please double-check,' which is far safer than silently handing you a wrong answer. Two honest caveats: (1) this clearly burns more tokens and will exhaust a free quota faster, so it's not worth running on every question — save it for ones where the answer has to be right; (2) it's still possible for all three paths to be wrong (if the problem itself is stated incorrectly or systematically misunderstood) — voting reduces risk but doesn't guarantee correctness, so for numbers that really matter, run the calculator yourself as a final check. Also, spell out every known condition in full — if you leave one out, the model will assume a value, and all three reasoning paths will skew the same way.

請用「自洽投票」的方式處理下面這道需要算對的題目：同一題，你要用三條彼此獨立、思路不同的方法各算一遍，再比對結果取共識。不要算一次就交卷。

【題目】
[題目]
【已知條件】[已知條件]
【要的答案形式】[答案形式]

請照以下流程：

第一步：路徑一。從頭把題目算一遍，把每一步算式和理由寫出來，最後標「路徑一答案：○○」。

第二步：路徑二。換一個不同的切入方式重算（例如換算順序、換公式、用反推驗算），同樣寫出過程，標「路徑二答案：○○」。不要偷看路徑一、要真的獨立重想。

第三步：路徑三。再換第三種方法算一遍，標「路徑三答案：○○」。

第四步：投票與裁決。
- 若三條路徑答案一致：直接給最終答案，並說明你對它有信心。
- 若三條不一致：列出分歧在哪一步、哪個版本最可能對、為什麼，挑出共識答案，並明確提醒我「這題出現分歧、建議自己再核一次」。

最後用【要的答案形式】給出乾淨的最終答案。全程台灣正體中文、金額用新臺幣、計算過程保留讓我能跟著核對。
