"Mathematics?" Xia ruofei was a little surprised. He couldn't help but ask,"could it be a chicken and rabbit in the same cage?"

He knew that the standard of mathematics in ancient China was not very high. Of course, the development of mathematics around the world was still in its early stages. Including "nine chapters of arithmetic", it only appeared in the Western Han Dynasty, and the time of Yuntai and the others should be the Qin Dynasty.

Layman Yuntai was also stunned and asked,""What do you mean by chicken and rabbit in the same cage?"

Xia ruofei thought about it. The problem of the chicken and rabbit in the same cage should have been first recorded in the sun Zi computational Canon, which appeared about 1500 years ago, far later than the era of Yuntai scholar, so it was normal that he did not know the classic problem of the chicken and rabbit in the same cage.
