The story of Arabic numerals; Euler changed his father’s sheepfold with mathematical wisdom; Han Xin inspect his troop which means the more the better; the mathematical principle in the fable called “Shou Zhu Dai Tu” (a man waits every day under the tree, in the hope that a hare would kill itself by crashing into a tree trunk)…There are so many fantastic and interesting stories about mathematics in human history!
