Jakow Trachtenberg - Who derived his own Speed Math in Nazi Concentration Camp - Trachtenberg System

[@jammypammer1986]

His focus helped him to keep his sanity while he was in hell. Even more amazing is that he survived seven years in that Nazi hell. Most died within the first year.

Why a photo of Wim Klein in the thumbnail, rather than Dr. Trachtenberg?

[@thecrashcartrulewsergebrow2473]

@@theoryfy your welcome...

[@piob9801]

I see that you also have a video on Vedic Math. Is one better than the other? Which one of the two would you suggest? thanks

[@theoryfy]

Both are good in their own ways..
And one should learn both for a deeper understanding..
But Vedic Maths has covered arithmetic in a more extensive manner..
