The Trachtenberg System is an innovative method of mental calculation developed by Jakob Trachtenberg. It utilizes the principles of “closeness to 10” and “closeness to 9” to simplify complex mathematical operations. By breaking down numbers into their constituent parts and applying specific techniques, the system enables individuals to perform calculations with remarkable speed and accuracy. This user-friendly approach is applicable in various settings and provides numerous benefits, including enhanced mental math skills, improved problem-solving abilities, and increased confidence in mathematical computations.
