[Basic Math and Pre-Algebra For Dummies (基礎數學與代數前期懶人包)] 介紹 #BloggerAds #閱讀 #心得分享

Once upon a time, you loved numbers. This isn’t the first line of a fairy tale. Once upon a time, you really did love numbers. Remember?
你曾經喜歡數字。這不是童話故事的第一行。你曾經真的很喜歡數字。回想起來了?

Maybe you were 3 years old and your grandparents were visiting. You sat next to them on the couch and recited the numbers from 1 to 10. Grandma and Grandpa were proud of you and — be honest — you were proud of yourself, too. Or maybe you were 5 and discovering how to write numbers, trying hard not to print your 6 and 7 backward.
可能你三歲的時候,外公外婆來訪。你在沙發上,坐在他們旁邊,從1背誦到10。外公和外婆為你感到驕傲—老實說—你也對自己感到驕傲。或者你五歲的時候,發現如何寫數字,很努力不要把6,7寫顛倒。

Learning was fun. Numbers were fun. So what happened? Maybe the trouble started with long division. Or sorting out how to change fractions to decimals. Could it have been figuring out how to add 8 percent sales tax to the cost of a purchase? Reading a graph? Converting miles to kilometers? Trying to find that most dreaded value of x? Wherever it started, you began to suspect that math didn’t like you — and you didn’t like math very much, either.
學習很有趣。數字很有趣。所以到底怎麼了?也許問題從長遠的分歧開始。或是整理如何將分數更改為小數。難道它只是用來知道如何添加8%的消費税變成售價?閱讀圖表?從英里轉換成公里?試圖找到最可怕的x值?不管從哪裡開始,你開始懷疑數學不喜歡你—你也很不喜歡它。

Why do people often enter preschool excited about learning how to count and leave high school as young adults convinced that they can’t do math? The answer to this question would probably take 20 books this size, but solving the problem can begin right here.
為什麼人們進入學前班時,興奮地學習如何計數。當離開高中時,年輕人說服自己他們不能算數學?這個問題的答案可能需要20本這樣大小的書,但解決這個問題可以從這裡開始。

I humbly ask you to put aside any doubts. Remember, just for a moment, an innocent time — a time before math-inspired panic attacks or, at best, induced irresistible drowsiness. In this book, I take you from an understanding of the basics to the place where you’re ready to enter any algebra class and succeed.
我虛心的懇求你把任何懷疑放在一邊。記住,就一下子,一段單純的時間—在數學恐慌症發作之前或是誘發不可抗拒的困倦之前的一段時間。在本書中,我將會把你從基礎數學的理解帶到你已經準備好進入任何代數課並且成功的地方。

Somewhere along the road from counting to algebra, most people experience the Great Math Breakdown. This feels something like when your car begins smoking and sputtering on a 110 ° F highway somewhere between Noplace and Not Much Else.
在從計數到代數的道路上,大多數人都經歷了“數學大事故”。感覺就像你的汽車在43°C高速公路上開始冒煙,在某處發生劈啪聲時。

Please consider this book your personal roadside helper, and think of me as your friendly math mechanic (only much cheaper!). Stranded on the interstate, you may feel frustrated by circumstances and betrayed by your vehicle, but for the guy holding the toolbox, it’s all in a day’s work. The tools for fixing the problem are in this book.
請把這本書視為你個人的路邊幫手,並把我當成你親切的數學技師。被困在州際公路上,你可能會因為環境而感到沮喪並且被你的車子出賣,但對於拿著工具箱的傢伙來說,這一切都在日常工作中。解決這個問題的工具在這本書中。

Not only does this book help you with the basics of math, but it also helps you get past any aversion you may feel toward math in general. I’ve broken down the concepts into easy-to-understand sections. And because Basic Math & Pre-Algebra For Dummies is a reference book, you don’t have to read the chapters or sections in order — you can look over only what you need. So feel free to jump around. Whenever I cover a topic that requires information from earlier in the book, I refer you to that section or chapter, in case you want to refresh yourself on the basics.
這本書不僅可以幫助你掌握數學的基礎知識,也可以幫助你克服對數學的厭惡。我已經把概念分解成易於理解的區塊。因為基礎數學與代數前期懶人包是一本工具書,所以你不用一個單元或一個小節照順序閱讀—你可以直接跳到你需要的部分。每當我需要本書前面提供的資訊時,我會把那個單元或者小節告訴你,以防你想要回去更新自己的基礎知識。

Here are two pieces of advice I give all the time — remember them as you work your way through the concepts in this book:
以下是我一直以來給出的兩條建議—當您按照本書中的概念進行工作時,記住它們:

  • Take frequent break(經常休息)
    • Every 20 to 30 minutes, stand up and push in your chair. Then feed the cat, do the dishes, take a walk, juggle tennis balls, try on last year’s Halloween costume — do something to distract yourself for a few minutes. You’ll come back to your books more productive than if you just sat there hour after hour with your eyes glazing over. 每20到30分鐘,站起來並且將你的椅子推進去。餵貓、洗碗、散步、玩弄網球、試穿去年的萬聖節服裝—做任何能夠分散注意力的事。在你的眼睛休息後,你回到你的書時,比起你坐在那裏一個小時又一個小時,將會更有成效。
  • After you’ve read through an example and think you understand it, copy the problem, close the book, and try to work it through(在你閱讀一個例題並且覺得自己已經理解的時候,複製問題、關上書,試著自己去做做看)
    • If you get stuck, steal a quick look — but later, try that same example again to see whether you can get through it without opening the book. (Remember that, on any tests you’re preparing for, peeking is probably not allowed!)如果你卡住,偷偷看一下。但之後在沒有看書的狀況下,再重新寫一次例題。(記住,你所準備的任何考試,偷看是不被允許的)
