"Good evening, third brother."
"Hello."
Yuchi walked over, and the maid wisely stepped away.
"Oh my! Uncle! You're here!"
As soon as little Ximo saw her uncle approaching, she transformed into a sloth, clinging directly to Yuchi's neck, swinging back and forth, giggling like a newly hatched chick.
"Haha, studying arithmetic, are you?"
Yuchi cheerfully hugged little Ximo, then sat on the stone bench, grabbing a book to take a look.
Similar to ancient China's 'Nine Chapters on the Mathematical Art' from her previous life.
It mainly consists of nine major chapters, not just simple one, two, three, four, five, six, seven; the detailed content is quite complex and considerable in depth.
From a previous life perspective, the book begins with calculation methods for the area of plane geometric figures, progresses to rationing problems, then methods for square roots and cube roots, and finally various systems of equations and the Pythagorean theorem.
