The Trachtenberg System

The Trachtenberg System is a mental math method designed to make quick calculations, especially for multiplying numbers, by using specific shortcut rules and mental tricks. Developed by Jakow Trachtenberg during World War II for wartime emergencies, it simplifies complex multiplication through a set of easy-to-remember algorithms tailored for different digits and operations. Instead of traditional methods, it breaks down calculations into manageable steps, enabling rapid mental computation with practice. The system is efficient for mental arithmetic, helping users perform calculations faster and more accurately without extensive calculation techniques.
