The proof for the Chinese Remainder Theorem used in Number Theory was NOT developed by its first publisher, Sun Tzu.

The statement is true because the Chinese Remainder Theorem was not developed by Sun Tzu, who is best known as an ancient Chinese military strategist and philosopher. The Chinese Remainder Theorem is a mathematical concept used in number theory to find a solution to a system of congruences. This theorem has its roots in ancient Chinese mathematics, and there is evidence of it being used by Chinese mathematicians as early as the 3rd century BCE. However, Sun Tzu lived during the same time period but is not credited with the development or publication of the Chinese Remainder Theorem.
