《开亲歌》是苗族十二路酒歌中历史最长、篇幅最大、内容最多、流传最广的一路。它流传的中心地区是贵州黔东南的黄平、施秉、凯里等,这些地区几乎家喻户哓,无人不会唱。 数学几乎是伴随着人类从事社会生产劳动而产生的。过去苗族同胞是如何应用数学的呢?在《开亲歌》一书中有一鳞半爪的反映。其一是歌棒上的刻木记数,其二为降聘礼过程中的算术四则运算。 “Kinship” is the longest history of the 12th Miao wine song, the largest, most content, the most widely circulated. The central area of ​​its spread is Huangping, Shi Bing and Carey in the southeastern Guizhou province. These areas are almost household names and no one can sing. Mathematics is almost accompanied by human labor in social production. How did Miao compatriots use math in the past? One is the engraved wooden inscription on the stick, and the other is the arithmetic operation in the downgrading ceremony.
