Mathematics requires a certain talent; if you don't understand a problem, even a teacher's ten years of explanation would be useless.
Aside from that, it also requires a passion and practical skills.
Ning Xiao had never received formal tutoring in mathematics, and yet, back in Xiangcheng, he was already considered on par with Ren Wanxuan and Chen Zhu.
Latter on, he joined the enhanced class and, with guidance from Jiang Fulai, his long-term foundation and hard work meant that his current research on a project and direction was in no way inferior to Hu Yue.
There's no need to mention Bai Lian; she had already understood the concept of integration back in Dayong, where they used "A, B, C, D" instead of the simplified numbers of today. Previously, her master had only taught her about measuring land and constructing specific diagrams of riverbanks and water channels.
Modern science was a powerful addition to her arsenal.
