在數業時略去小數壓式。 可寫出來,其它用心算處可17×2等於147化35元 於35化第8,所以左邊的九烩敏爲8,面右這答案的九餘數也爲8可知計算及營。
至於濒法和除法的融算也相似,可依此類推。
B+2-4
二十九餘數齡算法,簡捷神速,一宗後長的計算往往可用整分鐘的時間,既不用任何阡寒器械 甚至也不用勷筆,而確用簡辈的心算便可除定計算有沒有錯誤,如果您是一個老闆一個慈国 善用此法,打開一頁頓簿用是分鐘心算限可知結帳是否有體。如果您是一個統計強,計算造成, 理工學生,在完成一宗漫長的計算後,用此法來鹼算寫會深深體會到它是一弧所雄神法的數
但九餘數跟耳法有下列兩個缺點:《1》 在九餘數酸算法中9和0的九於數都篇0,因此答 案中的數字如果潮掉9和都是蠢不出的。(2)因篇一個數的九餘數個央定於組成該數的有效 数字的大小而周式排列順序無關,所以宮數中如果將鎖數字的順序也是鹼不出的
例如25+16041如果將41塊或14其无餘戴式仍成立,所以不能独出這種錯誤。

Paper: 11
National parks are very important to certain countries of Africa in the sense that they attract tourists - what we call “modern pilgrims and
travellers. The tourists bring in a large amount or money for the country as money is defrayed in the national parks themselves. Besides this, as the tourista tour around the country at large, they have to sperul money on transport, accomodation, equipment, photography and souvenirs.
Nowadays, many tourists. come to East airica ad South Africa for the sake of visiting the national parks and wild-life reserves. They also visit Mozambique:for the game reason and, in the near-iuturo, *Central Africa, too, will be crowded with tourists
based . an exactly the same ground Tourism le contimma Ily Tine reasing in importance throughout Africa's wild- flife area, and in Kenya, for instance, has already bet me the second largest source of national revenue, Caringing in for the country a sum of over eight
nd 1lion pounds Provided that there is peace all over
the world, tourism will still be the increase | bringing in more revenue for the country:
As the west progresses and becomes more and more prosperous, as the number of people increase, and as commerce and industry develops, more and more people will want to escape farther and farther from its results, in the shape of over-large and over-crowded cities, smoke, noise, boring routine, and the over- mechanization of life. In time, air travel will certainly become cheaper and more popular, and wil take more people farther efield.
At present, the revenue derived from tourism in East Africa is well over ten million pounds. It may be prophesied that the revenue will increase at least five-fold, or even ten-fold, in the next ten years, provided that the business is well organized. It will be necessary to improve access to the national parks and accomodation within them, catering for those who like comfort and for those who prefer a moredo it yourself holiday; to provide museums arid guides; to maintain a really adequate staff of wardens scientists and game scouts, good fencing and anti- poaching measuresy and to produce the right-sort of publicity.
It will be necessary to work in with travel and tourist agencies to make the most of holiday tours, to set up new national parks, and to open up new areas, such as parts of the coast and uplands, for the enjoyment of visitors. All this must be done in order that the national parks will not be over-crowded, which would spell their ruihation as already at some: seasons some of the roads in the Kruger Park are? overcrowded with cars full of tourists,
The improvements of the national parka, the extension of the national parks, and the opening up of new, national parks will cost money, and not asma 11: sum of money at that. So far, game departments an national paris. have been among the most neglected at government departments in Africa: now can they be provided with this extra finance? One solution is for the African territories to co-operate and make reasoned appiication to some United nations agency: Fór a loan to develop their tourist trade. In this way, they may stand a good chance of getting it. As tourism 13 an efficient means of increasing the Country a revenue, it 19 indeed worth while to think. of an effective way of obtaining the money necessary for the improvement, and extension of the nationel perks and wild-life reserves. As time goes by, more and more people will appreciate the importance of trese national parks and wild-life reserves and will. endeavour to eat them up in their own lands in the hope that national revenue will thus be increased
