Re: [問題] 請問幾題機經
※ 引述《paulwuuu (砲屋)》之銘言：
: 之前有板友分享
: smash : break = stalk : follow (板友wrest : take說錯？？)
: 可是我覺得他選的才是對的阿
: 應該是violently break和violently take
: 大家覺得呢？？
小弟認為smash : break = wrest : take 是對的
: -------------------------------------------------------------
: 還有一題計量
: 4. If the range of 6 consecutive positive numbers is 6.8 and
: of 7 consecutive numbers is 13.2. If none of these numbers
: in the two groups are same, then find the range of the 13
: numbers?
這題算不出來 = = 難...
RANGE:Difference between largest number and smallest (最大減最小)
: -------------------------------------------------------------
: 在一題....sorry>< (不知道我國中怎麼畢業的～)
: set a: {15, 16, 17, 18, 19, 20, 21}
: set b: {10, 11, 13, 14}
: if each number of set a is added to set b, how many different numbers?
: 請問一下這兩個集合是怎麼加阿？？
: 是4個數字還是7個還是11個數字咧？？
: 感謝大家！！！
15+ (10 11 13 14)= 25 26 28 29
16+ (10 11 13 14)= 26 27 29 30
....
...
..
21+ (10 11 13 14)= 31 32 34 35
我都會用排法來看
25 26 28 29
26 27 29 30
27 28 30 31
28 29 31 32
29 30 32 33
30 31 33 34
31 32 34 35
所以是11個 這種類型題目 算過一次就知道要如何算了
