This is the impressive moment a young boy showcased his remarkable mathematical skills in China. Five-year-old genius Zhuzi solved middle school-level maths equations in Shanghai on June 19. Footage shows the child tackling a tricky formula on the whiteboard and counting with his hand. Within half a second, he answered the problem and looked at his father with a smile on his face after writing the solution. His father, who works in an IT-related role, said he regularly taught his son mathematics since he was born.
