ABCD is a rectangular geometry problems are known, △ EFD area = 2cm2, △ CDF area = 3cm2, seeking quadrilateral AEFB area. ■ Answers Express reporter Huang Xiaoyi Many white-collar workers back to the math teacher Recently, the spread of a "Adults over 15 minutes a solution of elementary school math problem" (as shown) on the network. If you think this belongs to the "elementary level" and some "contempt", and that you may wish to after work today try to solve it. You know, the reporter interviewed the day before took this question in the Pearl River New City as a financial institution financial planner Lin, he actually can not solve it! "Learn math would count the money line." Seeing this road geometry question, Mr. Lin's first reaction was: "this topic is missing conditions?" When a reporter told him that no extra conditions, Lin suddenly plunged into confusion. More than 10 minutes later,T2NP0d3MR1, he reluctantly smiled and said: "It is estimated over 15 minutes can not make come." Reporters also try to solve problems, "relations triangle side ratio and area ratio" use mathematical principles when high school learned in the almost 15 minutes to work out the answer: 5.5 cm2. Lin looked at the problem-solving process reporter, said:. "Mainly just in the problem solving process is very tight, can not remember the formula, in 10 minutes or I can put out the solution to a problem." This Road Elementary math also stumped Miss Li Lin's colleague, she only tried for 5 minutes, gave up problem-solving. "Geometric knowledge forget it does not matter, anyway, now have no access to." She said. Subsequently,jcPR8d5ijK, the reporters invited nearly 10 white-collar solving the mathematical problem, five liberal arts students born white collar showing "no start" and said in their daily lives will be "Math", he knows how to count money is enough. Most people do not remember trigonometric If you and Mr. Lin as not solve elementary mathematical problems, then you do not have to feel unworthy of student math teacher, because in the business district, most white-collar workers have learned the mathematical knowledge previously returned to the teacher,taglio capelli, still a clear conscience. Reporters in the Pearl River New Town Plaza, Spring interviewed a dozen white-collar place, more than half of respondents said they could not remember when high school trigonometric formulas Over 80% do not remember college mathematics calculus formula. Miss Lee in the vicinity of the office to work, said: "Even if I do not know will not trigonometric calculus, I was alive and well." Lin also said that a student has done a lot of geometric proofs, but if he do not necessarily do it. Sound Sound Whether they favor a mathematical get out of college entrance examination? White-collar workers in three school Have reduced the proportion of college entrance examination in English in various provinces and cities on the occasion of Mathematics also "lay the gun",costo extension prezzi,qhxzONOT5b, into the cusp of public criticism. A portal microblogging on the investigation, "the mathematics you get out of college entrance examination," the nearly Qicheng users to support mathematics get out of college entrance examination. Some users also ridicule, many years of hard study mathematics, today can only be used to buy food. Reporters interviewed a number of industries in the CBD white-collar workers, found that support for the college entrance exam to reduce mathematics content, white-collar workers were divided into three factions. ● Support School Mathematics abuse me a thousand times, but I love mathematics as Miss Wu, a real estate company in charge of financial affairs think, belong to the basic disciplines of mathematics to other disciplines learning subtle effect. "In the university school of economics, finance and other professional, if not good at math is really unable to move." Miss Nguyen certain client communications industry managers agree mathematical work affect certain industries is very large. She said, just to transfer Kong logistics department performance statistics, now began to regret their year was bad at math. "Now, after a lot of work faced ex-cel document data are dense, no love for mathematics, not really carry off." Part treat white-collar workers believe that mathematics can not be too utilitarian. Liberal arts students born Wong said: "Mathematics abuse me a thousand times, but I love such as mathematics." In her view, knowledge is a cultivation process, can not say do not see the obvious results do not learn. "To say useless, I think classical daily life more useless. But what our ancestors can not learn it, this connotation of personal accomplishment helpful. Geometric mathematical knowledge can at least enhance spatial imagination." ● Opposition Hard to learn calculus, do not have access even to buy food On a portal microblogging site do the survey indicated that the majority of users complained math problem too "strange, difficult, deep", thus becoming the victim of exam-oriented education. Friends who support the abolition of the reason math test "righteous" that "learn addition, subtraction, enough to take the world." When talking about mathematics get out of the entrance of the problem, a financial institution internship Miss Liu said: "The mathematics do not abolish, but to distinguish between the candidates of liberal arts mathematics simpler then like, college mathematics can be used as electives, not mandatory. credits. " Miss Liu showed reporters her cell phone, this phone to download a variety of computing software, including pre-tax after-tax wage comparison, the price discount calculation. "The past is to learn physics and chemistry, traveled world are not afraid, now a cell phone in hand fixed up. You see, with the phone, the mathematics do not have access even to buy food." She said. ● centrist Mathematics itself is not wrong, blame blame difficult deep examination Some white-collar mathematical kind of "love-hate" complex affair. Last year, media practitioners Ng graduated from East China University of Science,mq0qK1VlWh, PubMed lost due to work this year. She mathematics really love and hate, that "as also mathematics, mathematics also lost." "In the past my favorite language, but the language is always pull out the back. I do not like math, but math test scores has never dropped out of the top three classes. If there is no mathematics, I could not even pass the test university . "Miss Wu said that in 2012, after graduating from college,extension cheveux achat en ligne, she had planned to cross professional graduate studies, but did not think this is a mathematical pull hind legs, something was lost twice. Miss Wu said: "A lot of graduate school party were hanged at the high number of mathematics although this tree had brought advantages and disadvantages, but I do not agree mathematics get out of college entrance examination.." Work in the Pearl River New City financial planner Lin believes that mathematics itself is not wrong,QUqrPKVyS1, wrong in mathematics exam was too hard too strange too. He said: "Mathematics is like a brain gymnastics school science Needless to say, not good at math,J0n4W9AxjB, physical chemical and biological calculations lot more liberal arts students can not learn if you are at the time doing rote math too. You can exercise the brain. " However, as science students,obuUXv805N, he said,extension cheveux clip,WOR54D8B3t, do not weigh more now math exams. "A few days ago,tagli di capelli, I almost even junior high school nephew jobs usually do not." He said with a smile. & Nbsp; (Edit: SN091)
