Make sure that you watch the whole video before using this technique because it has some initial conditions.
Of course I checked where this interesting technique came from. First of all I found out that there are more videos like this in Metacalfe in a channel named glad2teach.
More information can be found in Glad2teach website. There is a link to Faster Math Trick Videos which offers more examples and a change to buy the Complete EasyCal Series (Around 30 such faster Math trick videos)
According to the site:
These amazing tricks of faster Math have been taken from a 5000 year old book called Veda ( The ancient Hindu Scriptures ). If the name Veda sounds familiar to you, that is because it is the same book which gave to the world Yoga and Ayurveda.
The site suggest that after watching the videos you'll want to throw your calculator out of the window. I can imagine that happening. Too bad I still need the calculator for more complicated calculations. In my opinion calculators are used too much nowadays, at least in
You should also check dutchalone’s StumbleUpon page. According to his profile

Hi Leena,
This was great. you're so much full of maths tricks. you're a great mathematician and I'm sure your students would be proud of you!
when i saw your post, the first thing that crossed my mind was 'hey, i hv seen this in vedic mathematics', and realised it is teh same :) long time back - 10 or 11 years- we used to read and discuss vedic mathematics :)
Leena,
I just showed my second grade son the magic of multiplying by nine. I felt his same excitement watching this. It is fantastic!
Its very interesting trick and such trick are very good in saving our time and very good for competitive examination.

就嚟到冬天,大家都應該好需要羽絨傍身。唔知你哋有冇試過買錯羽絨呢?可能你哋會覺得好煩惱,唔知點樣揀一件適合自己嘅羽絨,因為羽絨有好多牌子,同埋種類。小編知道各位希望保暖之餘,又唔想收埋自己嘅纖腰。小編相信應該冇人鍾意着一件「脹卜卜」嘅羽絨,但係大家買羽絨既主要目的系抵禦寒風,究竟點樣去平衡靚同埋保暖呢?今日Tutor Circle尋補嘅小編就會同大家介紹五款高質羽絨,而且性價比好高。如果大家想知道着邊件羽絨最適合不過,就記得要睇埋落去啦!
1. Moncler

Moncler羽絨
首先,小編要介紹Moncler羽絨。Moncler款式時尚百搭,公司經常聯同其他設計師一齊合作Moncler Genius企劃,緊密交流,以檢視產品有冇持續發展。另外,羽絨既保暖功能十分唔錯,不愧成為法國知名嘅羽絨牌子。Moncler羽絨褸既絨毛系嚟自法國Grenoble水鴨,絨毛柔軟輕盈。如果你成日都要去行山,或者進行戶外活動,呢件羽絨就啱囇你啦!可能你會問點解,等小編回答你地啦!因為水鴨既羽毛經常係水中浸泡,所以這些羽毛防水性高。絨毛同羽毛既比例更達至90:10,超級保暖,就算寒風遇襲,都唔使驚,簡直系「世界級」既羽絨外套。

2. Perfect Moment

第二,Perfect Moment係一個好出名嘅美國牌子,就連英國凱特王妃都有著呢件羽絨,佢哋主要售買滑雪衣服。羽絨外層既Toray Airtastic物料具防水透氣既物料,鵝絨同埋羽毛既比例系90:10,加埋羽絨有高領,可以保護我哋既頸部,極度保暖,而且仲仔時髦。不過,如果你淨係留喺香港,小編就唔係好建議大家買,因為香港嘅溫度冇咁低,小編驚你哋買咗,但係着唔到,相反,假如你成日都要去外國出trip,呢件羽絨就好適合你啦!
3. Aigle

第三,Aigle係一個休閒羽絨牌子,主要售買舒適既服裝,容易展示休閒嘅穿搭風格。Aigle既羽絨褸CP值非常高,內層搭配咗90/10既羽絨外套,讓你應付寒冷既冬天,而且,羽絨褸有防風裙腳,係可以拆出嚟,使用彈性十分高。羽絨褸嘅設計一啲都唔馬虎。羽絨有撞色設計,所以睇落去唔會覺得單調無趣,覺得沉悶,令你冇藉口唔鍾意呢件羽絨!
4.The North Face

第四,來自美國的羽絨和戶外服裝品牌,除咗擁有十分唔錯嘅保暖功能之外,品牌還經常與全球各地不同的時裝和街頭品牌一齊合作,為品牌增加一番有趣嘅風味,所以每次一出新款,大家都會好期待。無論係外地,定係香港,The North Face都大受好評,相信冇人唔識呢個牌子!上年The North Face同Sacai一齊合作,推出咗服裝系列。果然,服裝大有市場,深受一眾時尚愛好者喜愛,引起一場激烈嘅「搶購潮」。
5. Columbia

最後,小編認為大部分香港人都應該知道呢個時髦運動品牌!一提起保暖衣物,大家必定會諗起Columbia既羽絨服。無可否定,大家對呢個品牌都會有足夠嘅信心,佢係「羽絨界」亦有所地位,深受各位歡迎。近呢幾年,大家都會對Ommi Heat熱能反射系列嘅羽絨衣心動,忍唔住手買咗返屋企。

總結
