我lee家F.1都係學埋lee D數=.="

    3=(P-2)1/3
3(3)=P-2
9+2=P
  11=P
    P=11

I'am P.6 .
But I know how to計.
Because it is so easy.
I think this is P.4 Maths.

就本人程度…呢題應該係心算之後即刻寫答案

你呢種方法MC先有用....(不過MC會出這麼淺嗎...

跳步我真的是很想跳，但係阿sir話如果你慣左跳步上高D年級就會越跳越多，到時隨時比人扣晒D Step分，所以阿sir話低年級就最好寫詳細D，雖然就慢左D，但就唔會比人扣step分....

3 = (P-2) x 1/3
3 x 3 = (P-2) x 1/3 x 3
9 = (P-2) x 1
9 = P-2
9+1 = P-2+1
10 = P-1
10+1 = P-1+1
11 = P
P = 11
absolutely詳細step

這只會搞得人一頭霧水…
不過又真係好詳細XD

心算?我仲未到咁高深既程度xd

我諗F.2或以上絕大部份既人應該會識

那絕少部分的那些其中一個一定是我......
我當年搞到一頭霧水......
Yearly有題是難吹（比這難得多，不過亦難不到現在的我......）
直至不知幾時才做得很輕鬆（可能在做其他數時做做下懂得竅門吧）

3 = (P-2) x 1/3
3 x 3 = (P-2) x 1/3 x 3
9 = (P-2) x 1
9 = P-2
9+1 = P-2+1
10 = P-1
10+1 = P-1+1
11 = P
P = 11

詳細：

3 = (P-2) x 1/3
3 x 3/1 = (P-2)x 1/3 x 3/1
9 = P-2
9+2=P-2+2
11=P
P=11

非常簡單=V=
我諗F.2或以上絕大部份既人應該會識
不過佢可能對Ｄ數生疏左．．．

如果係我，我應該會係咁計: ...

那不是跳啊，看起來才是真正的正常STEPS@@
