《同文算指》 / Tongwen Suanzhi
《同文算指》 appears in EP259 与苗师傅漫谈徐光启：四百年前如何让人变聪明？ as an elementary arithmetic text that 苗伟 compares to a primary-school math textbook. The episode uses it to imagine a missed educational possibility: if positional notation, written calculation, and math study had entered institutions earlier, learning efficiency might have changed.
The source places the work beside 《几何原本》. Where Euclid anchors proof-based reasoning, Tongwen Suanzhi anchors the everyday calculation and school-curriculum side of 晚明西学东渐.
The page therefore belongs to the wiki’s learning-how-to-learn branch. Better mathematical tools matter when they reduce unnecessary language friction and let students practice reasoning rather than only decode difficult packaging.
