Double 11 drew near, mom took a fancy to a Ximen Zishuang to open the door on the net freezer, consider a home in used any better year old small freezer was changed. This freezer is in clean out treasure, Beijing east, Su Ning has 3 times sell. Mom asks me when pupil teacher, help her calculate calculate the freezer sex price that buys in which to compare highest, most be to one's profit. Double 11 during, 3 inn organize an activity respectively, in clean out cost price of the freezer on treasure 7499 yuan, when buying, need to pay deposit 150 yuan ahead of schedule, deposit is in double this days 11 can offset when 3 times price, next 11 paid end the money that day, if did not pay end the money that day, deposit is not retreated. Reach namely handle end money 7499 - 150×3 ＝ 7049 (yuan) , and deposit should be paid 150 yuan before Jiashangzhi, pay 7049+150 actually ＝ so 7199 (yuan) . In Beijing east on double 11 during buy, this freezer cost price 8198 yuan, but composition activity is full 7000 decrease 1000 yuan, namely 8198 - 1000 ＝ 7198 (yuan) . And in Su Ning double 11 during buy this, cost price is 8380 yuan, full 4000 decrease 500 yuan, namely 8380 - 500×2 ＝ 7380 (yuan) . Compare so, the price is to clean out treasure and Beijing of course east some cheaper. At that time, mom asks again: “ cleans out treasure and Beijing east the price after privilege is euqally similar, it which should choose is good that which should choose? I ponder over ” a short while, answer: “ of course Beijing east, clean out treasure to want prepaid deposit to just have privilege, and if do not think,was to forget to paid end the money that day, deposit still is not retreated. And Beijing east one pace reachs the designated position, go to the lavatory simply. The thing that besides cleans out treasure is in double 11 during the ability inside 7 days delivers goods, beijing east affirmatory however deliver goods 3 days. Although both price is similar, but we should choose quicker, more convenient terms of payment to buy. You say mother, be? ” mom nods, what “ says is right, you are the young husband of my home really, say so that do by you! ”
双十一临近了，妈妈在网上看中了一款西门子双开门冰箱，想把家里用了好些年又旧又小的冰箱换了。这冰箱在淘宝、京东、苏宁三家都有卖。妈妈请我当一当小老师，帮她算算在哪一家买到的冰箱性价比最高，最划算。双十一期间，三家店都分别搞活动，在淘宝上冰箱原价7499元，购买时需提前支付定金150元，定金在双十一这天可当3倍价格抵消，然后十一当天付尾款，如当天不付尾款，定金不退。即得出应付尾款7499－150×3＝7049（元），而应该加上之前所付定金150元，所以实际支付7049+150＝7199（元）。在京东上双十一期间购买，这款冰箱原价8198元，但作文活动是满7000减1000元，即8198－1000＝7198（元）。而在苏宁双十一期间购买此款，原价是8380元，满4000减500元，也就是8380－500×2＝7380（元）。这样一比较，价格当然是淘宝和京东更便宜些。这时候，妈妈又问：“淘宝和京东优惠后价格一样差不多，哪该选哪一个好呢？”我思考片刻，答道：“当然京东了，淘宝要先付定金才有优惠，而且假如不想买了或是忘了当天付尾款，定金还不退。而京东一步到位，简单方便。况且淘宝的东西在双十一期间七天内才发货，京东却承诺三天发货。虽然两者价格差不多，但我们应该选择更快捷、更方便的支付方式买。妈妈你说，是不是啊？”妈妈点了点头，“说的对，你真是我家的小当家，就按你说得办！”
One of carrying the life a bagatelle, I also reach finish talks: We should discover only attentively, go thinking attentively, can realise maths is actually beside us, because amount to learns nowhere to be absent, want to have the eye that a pair of meetings discover only so, mathematical mystery is explored by you.
通过生活中的一件件小事，我也得出了结论：我们只要用心去发现，用心去思考，就会认识到数学其实就在我们身边，因为数学无处不在，所以只要有一双会发现的眼睛，数学的奥秘就由你去探索。(文/陈籽竹)
