Hello. My name is Ralph Duncans Jr. I am an American living in Japan. I developed a preschooler friendly English for Japanese children. American preschoolers can benefit from it also. They could start reading in a couple of weeks. I developed a preschooler math program also. I can teach preschoolers math from multiplication to trigonometry in ten days. I developed a method that teaches preschoolers to solve algebraic equations like 3(x²) + 3 = 15 easily. It is crazy! Teach your kids advanced math now. It is truly easy! I taught my daughter at the age of 4 and half years old math up to calculus and it took six to six and a half months. I lived in Japan for over 27 years. It lots of fun. I had been very successful in Japan. Born in Ann Arbor. Out of the hospital straight to Detroit. Detroit made me smart in math. Move to Westwood, California. What a great experience. I was stationed at Clark AFB and Edwards AFB. It was very interesting. I traveled through Asia. I had many wonderful experiences. I even received free silver gifts of various types from a village chieftess in Thailand. Life is interesting. I am very grateful for the life I had the privilege to experience. I am currently writing a math to show adults to teach preschoolers to go from multiplication to trigonometry in ten days. 🇺🇸USAF Veteran Paypal: www.paypal.me/GS350JPN Twitter@grammarloves Twitter@mathforchildren Twitter@myenglishjp WhatsApp 819060690641 or 8109060690641 12132218203
