Mag nodded. He asked for a pen and paper and wrote down the 9x9 table. In order to explain it better, he wrote down the whole 81 terms. Then he explained the decimal system in detail.
People here were using the sexagesimal system, and it had more than 1,700 terms, so the multiplication and division of two-digit numbers and more were extremely complicated. One would be considered a mathematics expert here if he or she was able to do the division of three-digit numbers and more.
So, before spreading the 9x9 table, this complicated system had to be replaced. History has proved that the decimal system invented by the Chinese sages was the simplest and most universal system. This system and the 9x9 table together were enough to solve most of the mathematical problems in life. It was an era in which the ancient Chinese dominated the whole world in arithmetic.
