The electrode placements for the math protocol are illustrated in a previous post. For this protocol I will be using Vedic Math software.
Vedic Math is a very detailed Indian system of mental calculation. A wonderful skill if you are interested in mathematics. I will be doing basic arithmetic problems initially but with vedic math that means adding very substantial figures rapidly in ones mind.
I will brush up on my technique first then perform the TDCs protocol for 20 minutes.
For this session I will shave my head - which is largely bald anyway.
There are many sources for Vedic Math software and I did an extensive search some time ago.

Once you get a taste for mental calculation it becomes very rewarding.
