Paragraph of misshapen feet, rusty compasses, the hardships or uncertainties in an unstable society of too much history left on their body, never change almost. See the playing thing that be like is a child, get type to stand in geometry however left illustrious meritorious military service, often solve an one path difficult problem, a kind of Gan Tian emerges mind.
残缺的段尺，生锈的圆规，它们身上留下了太多历史的风尘，几乎从未更换。看似是小孩的玩物，却在几何领式立下了赫赫战功，每每解出一道难题，一种甘甜涌上心头。
Numeric. Regard maths as the person, what we often care is each result, enough and rigorous. It is 120 minutes everybody place is yearning at present, each brutal and ruthless figure is fair, was opposite is right, won't be won't, read aloud between the day is fastened poorly, symbol, unit, what want take into account, maintain meticulously under just can have accurate result, sometimes passing line earns a composition plunge into, fall sometimes again wander by full marks, numeric and incorrect the distance that pulled open several minutes with other at a draught, this course can reflect a difference between the person most, it often appears with grinding the attitude that press everybody at the moment, also be throw egg against rock only to its reflection and mining, but in everybody one anxious not is exhibited when, you are held out suddenly go out however. This kind of pleasure and fun, other course cannot touch.
数值。作为数学人，我们往往在乎的是一个个结果，足够严谨。目前一百二十分是所有人所向往的，一个个残酷无情的数字是公平的，对了就是对了，不会就是不会，一念之间天差地别，符号、单位，都是所要顾及的，精心保养之下才会有正确的结果，有时有及格线挣扎，又有时落满分旁徘徊，数值不对就一下子与他人拉开了好几分的距离，这门学科最能体现出人之间的差距，它常常以碾压的姿态出现众人眼前，对它的思考与挖掘也只是以卵击石，但在众人一愁莫展时，你突然挺然而出。这种快感与乐趣，是其它学科无法触及的。
Act herbaceous. The others course often is arrange the knowledge that is engraved in brain slightly, again copy out is copied on examination paper. And maths depends on extracting, one lot random hemp is spent brief the number that all knows for child of a Fu, as magic general and magical. Perform herbaceous action to also be shown accordingly, layer upon layer logic combines annulus annulus photograph to buckle closely, one pace defeats cause of formation also because of one pace, its world always is be charmed making a person. Each maths person had be toed have act herbaceous. The more difficult the more such, it already decay is a great project, had not allowed in brain issue it, through be on paper one step by step computation a bit ground goes building build, as masticatory tea, agonized hind it is long Gan Tian.
演草本。其余学科往往是把刻在脑子里的知识稍加整理，再誊抄于试卷之上。而数学在于提取，将一堆乱麻化简为一个妇孺皆知的数字，如同幻术一般神奇。演草本的作用也因此显现出来，层层逻辑紧紧结合环环相扣，成因一步败也因一步，它的世界总是令人神往的。每一个数学人都不能不拥有演草本。越是困难的越是如此，它已经蜕变为一个宏大的工程，脑海中已经容不下它了，通过在纸上一步步的计算一点地去筑建，如同咀嚼茶叶，苦涩后是长久的甘甜。
Thousands of years ago, ancient Indian created an arabic numerals; After thousands of years, I sit up before desk again, brooding the maths before is inscribed, resemble a moment ago same.
几千年前，古印度人创造了阿拉伯数字；几千年后，我再次端坐在书桌前，沉思着眼前的数学题，就像刚才一样。
