I want to do 10 clases online with the world’s foremost mental math expert: JEONGHEE LEE. I need two more persons for to have a 60 % discount in the clases:

10 classes of 1 hour each for 40 $ each class.

Classes are in english.

You learn the basics of how to use a physical abacus followed soon by mental math techniques.
Once you have the basic mental math techniques down, then you will learn flash anzan.
You will need additional few hours training to learn to multiply and divide, but obviously need many hours of practice and additional lessons to master those skills.)
They would send you an abacus and initial textbook for $75 plus shipping and handling
JEONGHEE LEE IS MY IDOL. She is 54. She broke the record of memoriad additions 10 task for adding ten 10digit numbers in 100 seconds. Also she have the world record in memoriad tasks of:
Multiplication,
Division.
Flash anzan marathon.
JEONGHEE LEE IS THE ONLY KNOW SOROBAN ABACUS MASTER TO HAVE REACHED THE ELEVENTH DAN. IF ANYONE CAN EXPLAIN WHAT MEANS ELEVENTH DAN, TELL ME PLEASE!!!.
Jeonghee can even do 10 tasks for adding ten 10digit numbers FASTER THAN THE RECORD like you can see in the last video I put below. Also you can see Jeonghee doing flash anzan adding 51 four digit numbers while she having a conversation!!!:
In the last video Jeonghee Lee is adding large numbers with the total digits of 1250 in 92 seconds which means… SEE CREARLY WHAT THIS MEANS:
73,6 SECONDS at that speed in memoriad 10 tasks addition (1.000 dígits) = 7,36 s every 10x10 ADDITION!!!!!!!!!!!!!
AND MEANS THAT SHE ONLY HAVE 0,0588 SECONDS TO SEE EVERY DIGIT!!!
THAT IS VERY DIFFICULT FOR THE HUMAN EYE AND BRAIN.
Like I said, I need two more persons for to have a 60 % of disccount in the clases with JEONGHEE LEE.
