Testing once again....
let $S= (n_1,n_2,\cdots)$ denote the collection of those positive integers that do not involve the digit 0 in their decimal representatioin. (For example. $7 \in S$ , $101 \notin S$ ) show that $1/n_1+1/n_2+\cdots$ converges and has a sum less that 90

(For example, $a \in b$ )
有時得有時唔得嘅
正雖然唔識用但有得睇都好
d code其實好易用, 不過等khinchin巴打test下先啦

裝左
你要打 $ \$ $ 包住你要打的數學符號
例如 我 打 $ \$ $ \alpha \beta \gamma$ \$ $, 會出現 $\alpha \beta \gamma$

我去學術台開post, 等我陣, 廢事洗站務台
不過我都唔係太記d code (雖然基本都ok), 如果有熟o既巴打到時幫手指點下
