When I show to my children they were amazed and understand easily of what they learned at school but never get it clear. You know how schooling in Thailand, education here is mostly memorising and answer question ! So we parent have to help our children understand by external help. Your applest is very helpful tool. Thankyou for your contribution to people of the world. With best rgds. Amrat Chawla.
