Amul Qiqige, a Mongolian girl who studied under the master of astronomy and calendar Guo Shoujing, carries with her family the Miao medical wisdom and the feeling of helping the world. When the Persian giant Nasir al-Din used the "compound profit" algorithm to exploit most traders, she was keenly aware of the "exponential poison" that devoured wealth. From night market scheming duels to Khan court policy games, Amul uses Tianyuan magic as his blade to design fair lending formulas and outsmart the lustful caravans. She did not use violence to control violence, but based on arithmetic, integrating Miao's understanding of "balance" and medical science's pursuit of "eliminating evil and strengthening the right", promoting the birth of the "Commercial Tax Fairness Regulations", making mathematical wisdom a good way to maintain business order, and composing a legend of arithmetic helping the world in the fireworks of Yuan Dynasty. See how the calculator clears the fog with calculation chips and measures fairness with formulas!
