Oral arithmetic and quick mental arithmetic are different from abacus mental arithmetic and palm mental arithmetic. The fast mental arithmetic invented by Niu Hongwei, a teacher in Xi 'an, mainly trains children to do addition, subtraction, multiplication and division quickly through certain rules in textbooks. "Quick mental arithmetic" helps to improve the order, logic and sensitivity of children's thinking and behavior, and trains children's eyes, hands and brains to react quickly. The calculation method is consistent with primary and secondary school mathematics, so it is very popular with children and parents. ?
