And nowadays in China, fewer and fewer exams allow the using of calculator. For example, the National College Entrance Examination forbid to use any type of calculator except Shanghai City. You know this exam is actually the most important exam in a Chinese's life. So many parents treat the calculator as a monster that can make their kids weaker in solving math problems by hand calculation and forbid their kids to use it. Most of the calculator-allowed exams are just support the usage of scientific calculators,too. Not just almost no stage for calculators in exams, In daily use many people choose apps like geogebra or mathstudio in their smartphone. So few people in China has a real graphic calculator. Many people are even don't know how to use a scientific calculator now.
