Biography
方中通，桐城人。
清史稿卷五百六 列传二百九十三：
方中通，字位伯，桐城人。集诸家之说，著数度衍二十四卷，附录一卷。言：“九章皆出於句股，环矩以为圆，合矩以为方，方数为典。以方出圆，句股之所生也；少广，方圆所出也。方田、商功，皆少广所出。一方一圆，其间不齐，始出差分，而均输对差分之数，盈朒借差求均。又差分、均输所出，而以方程济其穷。度量衡原出黄锺，粟布出焉，黄锺出於方圆者也。”又言：“古法用竹径一寸长六分二百七十一而成六觚为一握，后世有珠算而古法亡矣。泰西之笔算、筹算，皆出九九。尺算即比例规，出三角。乘莫善於筹，除莫善於笔，加减莫善於珠，比例莫善於尺。”其珠算归法，三一三十一，四一二十二之类，“十”字俱作“馀”字。其尺算以三尺交加，取数祗用平分一线。时广昌揭暄亦明算术，与中通论难日轮大小，得光肥影瘦之故，及古今岁差之不同，须测算消长以齐之。一昼夜人一万三千五百息，每息宗动天行十万里有奇。别录为一书，曰揭方问答。
