The quick calculation of the brain and the brain is the only way to perform simple operations without any physical objects. Mental arithmetic is different from "abacus mental arithmetic" and "palm arithmetic", and neither abacus nor fingers are used. This is a fast calculation method invented by Xi An Niu Hongwei.
Patented teaching methods for quick calculation of heart and brain (mental calculation, mental calculation, quick calculation and pen calculation) are the same as those used in primary school mathematics, which is the best way for children to pass oral calculation and pen calculation in primary school.
Introduction:
China's education system is exam-oriented education, and the standard for testing students is exam transcripts, so students' main tasks are to take exams, answer questions and write with a pen. Students in exam-oriented education should get high marks, and writing arithmetic training is the main line of teaching.
Written calculation does not use any physical calculation, regardless of horizontal, vertical, and even addition and subtraction can be calculated freely. The rapid calculation of heart and brain begins with the most basic concept of number, which is synchronized with primary school mathematics.
But the teaching method is simple, and students are easy to learn and accept. In the teaching center, brain speed calculation simplifies complex problems and visualizes abstract and boring mathematical concepts. The advantages of quick calculation of mind and brain can be summarized in four words: more, faster, better and cheaper.
