Pingyang princess said: "Erlang there, I will send someone to continue to follow up, exchange what you need, Youyang and go to your business."

"It's just some strange skills, but it should be such a long speech? Are you exaggerating? "

The king of Qi, who had been watching with cold eyes and drinking alone, couldn't help laughing. Xue Lang was not displeased. It is not surprising that the ancients had such an idea. Compared with the song, Ming and Qing Dynasties, the Tang Dynasty was enlightened in mathematics.

Xue Lang said seriously: "the king of Qi is wrong. I have heard a saying since my childhood that mathematics is the king of science. From building houses to building houses, building city leaders and buying vegetables, we need to apply mathematics. "

The king of Qi scoffed and was about to speak when the announcement from the palace people outside came: "the king of Qin is here!"

Xue Lang took advantage of the situation to accept the words, and did not give the king of Qi the idea of popularizing science and correcting ideas. When he talked about mathematics with the king of Qi, Xue Lang felt that it was almost like casting pearls before swine, which was a waste of effort.
