If your baby calculate mentally, please tell me how old is your child?
When did you teach him / her math?
Which method did you use?
Do you think it is useful to teach math with this methods (right brain education)?
If we teach math with right brain education when child go to school and learn with left Brian education, does it make mistake for him / her?
I want to teach math with 63 days Shichida methods and I can’t understand how I teach math with this method. (I just read an Equation and show answer with dots) how can my child understand math?

does he memorize these Equations?
Please help me with this problem.
