The 2nd Online Entrance Examination Mathematics Contest is being held at "Beautiful Story of High School Mathematics", one of the largest mathematics sites in Japan operated by Bend Co., Ltd.Six good questions, just like the actual entrance exam, where you can test your true math skills, are open to the public for free.
In the first session, which was attended by nearly 1200 people, it was well received that it was possible to prepare for entrance exams for mathematics online and to know its own national ranking, but it was biased toward a slightly difficult problem.Although the difficulty level of the following 1nd tournament was reduced overall, like the 2st tournament, there are some difficult problems that cannot be solved without careful consideration.
In particular, the fourth question is an applied problem for science, and it is necessary to have the ability to process information correctly and calculate it to the end.In order to solve within the time limit of the entrance examination, the speed of calculation is also required, and in the answer explanation, we will introduce how to make a policy for that and a good calculation method.
For the sixth question, we have prepared a difficult question to think carefully, taking advantage of the feature of this contest that there is no time limit.The ability to observe the situation and formulate the correct policy has been fully tested, there are multiple solutions, and the answers that come out are interesting.The deadline for submitting answers is 6:8 on August 31st.
