期待大家都能在被妖魔化的數學裡,找到數學可愛的一面,它會讓你賺大錢,並且實現商業的最高價值:服務人群。――謝文憲
數字不但非常有趣,而且很有用!
如果你覺得數字枯燥、毫無用處,那你就錯過了一門連接現象與本質的語言,錯過了理解商業世界最底層邏輯的終極方法。
持續成功的底層邏輯,只須用一個數學公式即能破解:
提高整體成功率的方法:一是提高基礎成功率,二是增加嘗試次數。
而什麼是「商業世界的加減乘除」?
商業世界的生命體是企業,企業也需要謀求個體的生存繁衍(競爭),以及群體的共生繁榮(合作)。
有時候企業選擇競爭,有時候企業選擇合作,但目的都是永續經營。
合作與競爭可能在同一個維度上,也可能在不同的維度上。
只要理解競爭合作、同維異維,你就能理解什麼是「商業世界的加減乘除」。
本書重點
四則運算:基於數字的加減乘除在商業世界具有獨特價值,掌握這個工具,你就能從數字中開採出「礦藏」。
笛卡兒坐標系:養成「五維思考」的習慣,你就能升維思考、降維執行,從而更好地理解商業世界,在創業道路上所向披靡。
指數和冪:指數和冪以及它們背後的數學規律,幾乎決定了你在商業世界裡能獲得多大的成功。
變異數與標準差:掌握住衡量差異性的重要工具,就能在經營企業、管理團隊、製造產品時正確評估該縮小或擴大,確保企業的良性運轉。
機率與統計:這個世界從來都是不確定的,創業就是管理機率。
博弈論:你在決策時,別人也在決策。這些決策相互影響,甚至相互交織,從而使那些奇妙的決策顯得很愚蠢,使那些莫名其妙的決策產生奇效。

Not for sensitive skin
Size: 2.5 Fl Oz (Pack of 1)
I have combination skin, prone to acne, and sensitive skin. Even though this is labeled as non-comedogenic and best suited for oily skin, I still experienced acne because the consistency of the sunscreen is really thick. It makes it hard to blend (really hard) and upsets my skin.
It also smells a lot like alcohol, more so than most sunscreens, even those from this brand.
I bet it's good for some skins but it simply wasn't for me.

Finally!
Size: 2.5 Fl Oz (Pack of 1)
I have been looking for a sunscreen that does not breaks me out or irritate my eyes and this was perfect. I wash my face in the morning and I put this sunscreen on. I don't need to use moisturizer since this is enough. It does leave my skin glowy which I like but not greasy. I notice even my dark spots are fading but because I do use this everyday. My skin is tan and it does not leave a white cast. I love it. If you have acne prone skin, oily and sensitive give this a try.

Finally! An SPF Hubby will wear!
Size: 2.5 Fl Oz (Pack of 1)
I've bought my husband at least a dozen SPFs--everything from drugstore to premium brands--and he won't wear any of them. He's 64 years old with oily, extremely sensitive skin (rosacea and dermatitis), and a tendency to sweat a lot in the summer heat, as he's very active. As for SPF, he hates the white cast, how heavy it feels on his skin, and how his eyes burn when he sweats and the SPF gets in them. But I keep trying. Since Eucerin was the only SPF I was able to tolerate after radiation, I tried this one for him. It's the only one he's liked. There's some white cast initially but it settles quickly. He says the lotion doesn't feel heavy, hasn't caused any irritation or breakouts, and doesn't bother his eyes either. He actually wears this one!!! I'm thrilled! Thank you, Eucerin!

Good sunscreen
This sunscreen works well, and has coconut oil base, which is good for your skin. The cans have an adequate amount in them, but I would also like to see something twice their size, if that's possible.
